Brugada Syndrome

Brugada syndrome is an inherited heart rhythm problem. It affects the way tiny “ion channels” move electricity in the heart’s cells. This can create a special ECG pattern in the right chest leads (V1–V3) called a type-1 Brugada pattern: a coved ST-segment elevation with a negative T wave. People with this condition can be at risk for dangerous fast rhythms from the bottom chambers of the heart (ventricular tachycardia or ventricular fibrillation), sometimes during sleep or fever. The heart muscle is usually normal in structure; the problem is in the electrical system. OUP Academic+2NCBI+2

Brugada syndrome is a genetic heart-rhythm disorder where the heart’s lower chambers (ventricles) can suddenly beat in a fast, dangerous way and sometimes stop. The problem is electrical, not a clogged artery. Many people feel fine until a trigger—like fever, certain medicines, or heavy alcohol use—sets off a dangerous rhythm. The typical ECG shows a “type 1” coved ST-elevation in the right chest leads (V1–V3). The main proven protection is an implantable cardioverter-defibrillator (ICD) for people at highest risk; in selected patients with repeated shocks or electrical storm, targeted catheter ablation helps. Medicines can help in emergencies or when an ICD is not possible, but drugs do not cure the condition. Family members may also need evaluation because it can run in families. guardheart.ern-net.eu+2European Society of Cardiology+2

Fever makes Brugada syndrome more dangerous because heat further weakens sodium channels in the heart. That can unmask the ECG pattern or trigger life-threatening rhythms, which is why fast fever treatment is essential in both adults and children. PMC+1

The most commonly involved gene is SCN5A, which encodes the main cardiac sodium channel. Faults (variants) in this gene can reduce the inward sodium current, making the right-ventricular outflow tract electrically unstable. Other, less common genes that affect sodium or calcium currents can also be involved. Many people, however, have no identifiable gene change even though they clearly have the syndrome. NCBI+1

Brugada syndrome is seen worldwide but is more common in men and in some Southeast Asian populations. It is one cause of “sudden unexplained nocturnal death syndrome” (SUNDS). Some triggers can unmask or worsen the ECG pattern or cause dangerous rhythms, such as fever or certain medicines. PMC+2ScienceDirect+2

Other names

Brugada syndrome is also called: Brugada pattern (for the ECG), Brugada disease, idiopathic ventricular fibrillation with right precordial ST elevation, and it is linked in the literature to sudden unexplained nocturnal death syndrome (SUNDS) in parts of Asia. The ECG hallmark is often called the “Brugada sign.” OUP Academic+2Life in the Fast Lane • LITFL+2

Types

Clinicians mainly classify ECG patterns:

1. Type-1 (diagnostic pattern): Coved ST-segment elevation ≥2 mm in ≥1 of V1–V3, followed by a negative T wave. This is the only standalone ECG pattern considered diagnostic when seen spontaneously or after a drug challenge, together with supporting clinical features per consensus criteria. Life in the Fast Lane • LITFL+1

2. Type-2 and Type-3 (suggestive patterns): “Saddle-back” or less pronounced ST elevation. These are not diagnostic by themselves. They may prompt a sodium-channel blocker challenge (for example, ajmaline or flecainide) to see if they convert to type-1. Life in the Fast Lane • LITFL+1

Diagnosis today is guided by the Shanghai Score System, which combines ECG pattern, symptoms, family history, and genetics. A higher score means more diagnostic certainty and can help with risk thinking. PubMed

Causes and triggers

Important idea: In many people, the underlying cause is a genetic tendency. On top of that, triggers can unmask the ECG pattern or provoke a dangerous rhythm. Here are 20 well-described causes or triggers:

1. SCN5A pathogenic variants: Reduce the heart’s sodium current and destabilize the right ventricular outflow tract. NCBI

2. Other ion-channel gene variants (e.g., CACNA1C, CACNB2, CACNA2D1, KCND3, SCN1B/2B/3B, RANGRF): Less common, but also alter sodium or calcium currents. NCBI

3. Fever: Raises heart temperature and can reveal the ECG pattern or trigger arrhythmias; treating fever is essential. NCBI

4. Sodium-channel–blocking antiarrhythmics (class I), e.g., flecainide, ajmaline, procainamide (used diagnostically but risky unsupervised): Can provoke type-1 pattern or arrhythmias. ijcva.org

5. Psychiatric medicines (some tricyclics, certain SSRIs), anesthetics, and other listed drugs: Avoid or use with special care per BrugadaDrugs.org. brugadadrugs.org+1

6. Cocaine and other recreational stimulants: Increase arrhythmia risk via ion-channel effects and autonomic surges. heartrhythmjournal.com

7. Heavy alcohol intake or large meals (vagotonia): May increase vagal tone at night and promote arrhythmias in susceptible people. NCBI

8. Electrolyte disturbances (e.g., low or high potassium, low calcium): Change electrical stability and can unmask ECG changes. NCBI

9. Autonomic fluctuations (rest/sleep, high vagal tone): Many events occur at night during rest. NCBI

10. Male sex: Men have more pronounced right-ventricular Ito current, making the ECG phenotype more likely. OUP Academic

11. Southeast Asian ancestry: Higher prevalence and historical link to SUNDS. PMC+1

12. Hyperthermia (sauna/heat illness): Similar mechanism to fever; higher temperature accentuates channel dysfunction. NCBI

13. Dehydration or acute illness: Can shift electrolytes and autonomic tone. NCBI

14. Bradycardia or pauses: Long pauses at night can set up arrhythmias in a susceptible substrate. NCBI

15. Right-ventricular outflow tract conduction delay (functional): Local conduction abnormalities underlie the ECG signature. OUP Academic

16. Certain antibiotics or antifungals listed as “avoid/prefer avoid”: Potential to unmask the ECG pattern. Check authoritative lists. brugadadrugs.org+1

17. Lithium and some mood stabilizers (on avoid lists): Sodium-channel effects can be problematic. brugadadrugs.org

18. Class IC antiarrhythmics outside monitored testing (flecainide/propafenone): Strong sodium-channel block can provoke events. ijcva.org

19. Hypothyroid or hypothalamic states causing hypothermia are not typical triggers; the key temperature risk is fever/hyperthermia rather than cold. The main takeaway is to treat fevers early. NCBI

20. Unknown/idiopathic: Many patients have no identified gene or clear trigger, but the syndrome is still real and diagnosable by ECG + clinical criteria. PubMed

Symptoms and warning signs

1. Fainting (syncope), often at rest or at night: Due to brief fast rhythms that stop on their own. It needs urgent evaluation. NCBI

2. Seizure-like episodes during sleep: Caused by lack of blood flow to the brain from a sudden arrhythmia. NCBI

3. Palpitations: A sudden pounding or fluttering heartbeat. NCBI

4. Nocturnal agonal breathing (gasping): Can occur during dangerous rhythms in sleep. OUP Academic

5. Sudden cardiac arrest or near-arrest: Sometimes the first sign in previously healthy adults. OUP Academic

6. Lightheadedness or presyncope: Brief reduced blood flow from transient arrhythmias. NCBI

7. Chest discomfort not due to blocked arteries: Usually electrical, not structural. NCBI

8. Symptoms during fever: Fever can bring out the ECG pattern and symptoms; treat fever promptly. NCBI

9. Symptoms after certain drugs or alcohol binges: Triggers can provoke palpitations or fainting. brugadadrugs.org

10. Family history of sudden unexplained death (especially in sleep): A vital warning clue. PubMed

11. Family history of Brugada syndrome or characteristic ECG: Increases suspicion and Shanghai Score. PubMed

12. Night-time events after heavy meals or rest: Related to high vagal tone. NCBI

13. No symptoms at all: Many people are asymptomatic and found by ECG screening or family work-up. OUP Academic

14. Recurrent unexplained fainting in young or middle-aged men: A classic presentation. OUP Academic

15. Shock from an implanted defibrillator (for those who have one): Can signal recurring ventricular arrhythmias. NCBI

Diagnostic tests

A) Physical examination (what clinicians look for)

1. General exam and vital signs: Doctors check blood pressure, heart rate, temperature, and oxygen levels. Fever is especially important because it can unmask the ECG pattern and must be treated quickly. Structural findings are usually normal. NCBI

2. Cardiovascular exam: Listening for murmurs or signs of structural disease. In Brugada syndrome, the heart structure is generally normal; the problem is electrical. This helps separate Brugada from other causes of arrhythmia. OUP Academic

3. Neurologic checks after blackouts: To rule out a primary seizure disorder and to document seizure-like movements from a cardiac faint. History and witness reports guide next steps. NCBI

4. Temperature-focused assessment: Because fever is a known trigger, clinicians actively look for infection and advise aggressive fever control. NCBI

B) “Manual” bedside tests and simple maneuvers

5. Right precordial lead repositioning (V1–V2 placed one or two spaces higher): Moving V1–V2 to the 2nd or 3rd intercostal space can make a hidden type-1 pattern show up more clearly. This is a simple, non-invasive bedside step. Life in the Fast Lane • LITFL

6. Vagal tone observations (rest/sleep): Monitoring during rest or at night can reveal events; many arrhythmias happen when vagal tone is high. NCBI

C) Laboratory and pathological tests

7. Electrolytes (potassium, calcium, magnesium): Abnormal levels can mimic or unmask Brugada-like ECG changes; correcting them is important before confirming diagnosis. NCBI

8. Fever/infection work-up (CBC, inflammatory markers if needed): Because treating fever reduces risk; work-ups search for causes that can be fixed. NCBI

9. Toxicology screen when appropriate: Looks for stimulants or drugs on “avoid” lists that could provoke the pattern or arrhythmias. brugadadrugs.org

10. Genetic testing (starting with SCN5A): Helps confirm the cause, screen relatives, and contribute to Shanghai scoring. A negative result does not rule out Brugada syndrome. NCBI+1

D) Electrodiagnostic tests

11. Standard 12-lead ECG: The cornerstone test. A spontaneous type-1 pattern is diagnostic when paired with clinical criteria. Types 2–3 are suggestive. Life in the Fast Lane • LITFL+1

12. High intercostal ECG leads (V1–V2 higher): Increases sensitivity to detect the right-ventricular outflow tract pattern. Often done at the same sitting. Life in the Fast Lane • LITFL

13. Sodium-channel blocker challenge (e.g., ajmaline/flecainide/procainamide) in a monitored lab: Used for suspected cases with non-diagnostic ECG; can safely unmask a type-1 pattern when performed under strict monitoring. ijcva.org

14. Holter (24–48 h) or extended loop monitoring: Looks for intermittent type-1 pattern, pauses, or ventricular arrhythmias during daily life and sleep. NCBI

15. Signal-averaged ECG (SAECG): Research/adjunctive tool to detect late potentials; may reflect conduction delay in the right ventricular outflow tract. Risk value is debated. OUP Academic

16. Exercise or recovery-phase ECG protocols (selected cases): Some centers observe how the pattern behaves with autonomic shifts; not a primary diagnostic test. NCBI

17. Electrophysiology study (EPS): A catheter test that tries to induce ventricular arrhythmias. Its role in routine risk stratification is debated; it may help in selected patients under expert care. OUP Academic

E) Imaging tests

18. Transthoracic echocardiogram: Usually normal in Brugada syndrome; done to exclude structural heart disease that can also cause arrhythmias. OUP Academic

19. Cardiac MRI: Looks for subtle scar or structural disease; typically normal in true Brugada syndrome but useful to rule out look-alike conditions (e.g., arrhythmogenic cardiomyopathy). OUP Academic

20. CT coronary angiography or stress imaging (when indicated by symptoms): Not routine for Brugada, but can exclude ischemia if chest pain or risk factors suggest coronary disease. The main Brugada diagnosis still relies on ECG criteria and clinical context. OUP Academic

Non-pharmacological treatments (therapies & other measures)

1) Treat fever fast. Use antipyretics promptly whenever body temperature rises; fever is a well-known trigger for arrhythmias in Brugada syndrome. PMC+1

2) Avoid contraindicated drugs. Many medicines—especially some anesthetics, antidepressants, antipsychotics, and sodium-channel blockers—can worsen Brugada. Check a trusted list before starting any new drug. brugadadrugs.org+1

3) Limit alcohol and avoid binge drinking. Heavy alcohol intake can provoke ventricular arrhythmias in Brugada; moderation lowers risk. guardheart.ern-net.eu

4) Avoid recreational stimulants (e.g., cocaine, amphetamines). These can trigger dangerous rhythms and should be avoided. guardheart.ern-net.eu

5) Keep electrolytes normal. Dehydration or low potassium/magnesium can make arrhythmias more likely; rehydrate and correct abnormalities. guardheart.ern-net.eu

6) Infection care plan. Seek early treatment for infections (which raise fever) and have antipyretics at home. PMC

7) Family screening & genetic counseling. First-degree relatives should be evaluated; counseling helps families understand testing and monitoring. PubMed

8) Emergency plan for fainting (syncope). Unexplained fainting in Brugada warrants urgent medical review because it may reflect ventricular arrhythmia. guardheart.ern-net.eu

9) Wear a medical ID. A wallet card or bracelet that says “Brugada syndrome—avoid sodium channel blockers; treat fever” helps in emergencies. PubMed

10) Anesthesia precautions. Tell surgical and dental teams in advance so they can avoid risky drugs and monitor carefully. brugadadrugs.org

11) Sleep apnea evaluation if symptomatic. Treating sleep apnea can reduce cardiac irritability in some arrhythmic conditions; screen if you snore or are very sleepy. guardheart.ern-net.eu

12) Avoid extreme heat/sauna when ill. High temperature can unmask arrhythmias; skip heat exposure during or after a fever. PMC

13) Safe exercise habits. Routine exercise is fine for most, but stop if you feel dizzy, faint, or have palpitations; get checked before competitive sports if you’ve had symptoms. guardheart.ern-net.eu

14) Household CPR training. Family CPR training adds a layer of safety while waiting for emergency services. guardheart.ern-net.eu

15) Remote ICD monitoring (if you have an ICD). Remote checks help rapidly detect shocks or device issues and guide care. guardheart.ern-net.eu

16) Careful use of over-the-counter cold/flu products. Some contain risky ingredients; check Brugada-safe lists before use. brugadadrugs.org

17) Pregnancy and delivery planning. Most pregnancies are uneventful, but share your diagnosis with obstetric and anesthesia teams to plan safe drugs. PubMed

18) Avoid large, rapid temperature changes during illness. Rapid warming can worsen ECG changes during fevers—cool gradually and medicate. PMC

19) Prompt follow-up after any shock or faint. Recurrent events may need medication adjustment or ablation evaluation. guardheart.ern-net.eu

20) Psychological support. Anxiety after shocks or a new diagnosis is common; counseling improves quality of life and adherence to safety plans. ahajournals.org

Drug treatments

Important: there are very few medicines with proven benefit in Brugada syndrome. The core is acute isoproterenol for electrical storm and quinidine for preventing recurrent ventricular fibrillation or when an ICD is not feasible. Antipyretics treat a major trigger (fever). Electrolyte repletion may help stabilize the heart. I list the key agents below with FDA labels where available and clearly mark off-label use. I will not invent 20 drugs because that would be unsafe and misleading. guardheart.ern-net.eu

Isoproterenol (ISUPREL) — acute rescue in electrical storm (off-label).
Class: Non-selective β-agonist. Dose/time: Continuous IV infusion titrated in ICU to suppress recurrent VF/VT storms. Purpose: Temporarily raises heart rate and β-stimulation to stabilize electrical activity and prevent VF recurrences. Mechanism: Increases cAMP and calcium currents, countering the phase-2 re-entry thought to underlie Brugada VF; shortens action potential heterogeneity in RV outflow tract. Side effects: Tachycardia, arrhythmias, ischemia; contains sulfites (rare allergy). Evidence note: Widely recommended by expert consensus for Brugada electrical storm despite off-label status. FDA Access Data+2FDA Access Data+2

Quinidine (quinidine gluconate/sulfate) — chronic suppression (off-label but guideline-supported).
Class: Class IA antiarrhythmic (Na⁺ block with Ito/K⁺ effects). Dose/time: Oral, individualized dosing with ECG/QTc monitoring. Purpose: Prevents recurrent VF/VT or frequent ICD shocks; considered when ICD not feasible or as adjunct. Mechanism: Blocks Ito and Na⁺ currents, reducing the action-potential notch and restoring dome, which stabilizes RVOT substrate. Side effects: QT prolongation, torsades risk, GI upset, cinchonism; drug interactions. Evidence note: ESC and multiple reviews support quinidine in Brugada; FDA label exists for arrhythmias (not specifically Brugada). guardheart.ern-net.eu+3FDA Access Data+3FDA Access Data+3

Acetaminophen (paracetamol) — antipyretic trigger control.
Class: Analgesic/antipyretic. Dose/time: Standard adult dosing per label. Purpose: Lowers fever to remove a major Brugada trigger. Mechanism: Central COX inhibition lowers hypothalamic set-point. Side effects: Hepatotoxicity with overdose. Evidence note: Fever is a documented arrhythmic trigger in Brugada; antipyretic choice should avoid contraindicated combinations. PMC+1

Ibuprofen — antipyretic/anti-inflammatory trigger control.
Class: NSAID. Dose/time: Standard OTC dosing with food and renal/GI precautions. Purpose & mechanism: Reduces fever and inflammation; removes a key trigger. Side effects: GI, renal, bleeding risk. Evidence note: Use only if not on the Brugada “avoid” list or interacting drugs; check trusted lists. revportcardiol.org+1

Magnesium sulfate (IV) — adjunct when low Mg or polymorphic VT present.
Class: Electrolyte. Dose/time: IV bolus/infusion in monitored settings. Purpose: Stabilizes myocardium during ventricular arrhythmias linked to low Mg or prolonged QT; not a Brugada cure. Mechanism: Modulates calcium influx and suppresses early after-depolarizations. Side effects: Flushing, hypotension, respiratory depression with overdose. Evidence note: Supportive in ventricular arrhythmias; corrects a modifiable risk rather than Brugada substrate. guardheart.ern-net.eu

Potassium (oral/IV as KCl) — correct hypokalemia.
Class: Electrolyte. Dose/time: Per deficit and ECG/renal function. Purpose: Normalizes repolarization and reduces arrhythmia risk; treat low K⁺ promptly. Mechanism: Restores membrane potentials and conduction stability. Side effects: Hyperkalemia risk. Evidence note: Electrolyte optimization is recommended in arrhythmia care broadly; part of supportive Brugada management. guardheart.ern-net.eu

Drugs often not helpful or potentially harmful in Brugada include many class I antiarrhythmics (that further block sodium current) and some psychotropics; always check a dedicated Brugada drug resource and guidelines. Amiodarone is not consistently effective for Brugada VF and should not be relied upon alone. brugadadrugs.org+2brugadadrugs.org+2

Dietary molecular supplements

There is no dietary supplement proven to treat Brugada syndrome or prevent its lethal rhythms. Large trials in high-risk arrhythmia patients have not shown clear protection from fish-oil/omega-3s, and major societies caution against relying on supplements for heart-rhythm prevention. If you choose to use any supplement, do it only with your cardiologist and never to replace proven care (ICD, ablation, or indicated medicines). PubMed+2JAMA Network+2

Below are common supplements people ask about, with honest, simple guidance:

1. Omega-3 fatty acids (fish oil): Research in patients with ICDs did not show fewer dangerous shocks or deaths; some data link higher doses with more atrial fibrillation in certain groups. Do not use omega-3s to “treat Brugada.” PubMed+2JAMA Network+2

2. Magnesium (oral): Helpful only if your level is low; otherwise no proof it prevents Brugada rhythms. Check a blood level first. PMC

3. Potassium (dietary): Eat potassium-rich foods for general heart health, but do not supplement without labs and clinician guidance. OUP Academic

4. Coenzyme Q10: No robust evidence for preventing ventricular arrhythmias; discuss interactions with your doctor. PMC

5. Vitamin D: Treat deficiency for overall health; no evidence it prevents Brugada arrhythmias. PMC

6. B-complex/folate: No proof for Brugada rhythm prevention; follow dietary guidance instead. jacc.org

7. Curcumin, resveratrol, quercetin, taurine: Laboratory effects exist, but clinical arrhythmia prevention is unproven. Don’t rely on them. PMC

8. Electrolyte beverages: Useful for hydration during fever/illness; choose low-sugar options and check potassium content if on heart meds. guardheart.ern-net.eu

9. Multivitamins: No evidence they reduce cardiac events; not a Brugada therapy. PMC

10. “Heart health” blends: Labels often claim benefits without strong trials; avoid unless your clinician agrees. ahajournals.org

Immunity booster / regenerative / stem-cell drugs

There are no approved immunity-booster, regenerative, or stem-cell drugs for Brugada syndrome. Brugada is an electrical channelopathy, not an immune problem, and current regenerative or stem-cell treatments have no clinical role here. The safest course is proven care (ICD in those who need it, ablation in selected high-risk patients, trigger avoidance, and emergency fever treatment). I will not fabricate drug names in this category. guardheart.ern-net.eu+1

Procedures/surgeries

1) Implantable cardioverter-defibrillator (ICD).
What happens: A small device is placed under the skin with a wire in the heart. Why: It detects and stops life-threatening rhythms with a shock or pacing. Who benefits: People with prior cardiac arrest, documented VF/VT, or very high-risk features after specialist evaluation. guardheart.ern-net.eu

2) Catheter ablation of the RVOT epicardial substrate.
What happens: A catheter reaches the outer surface of the right ventricle; abnormal electrical areas are mapped and cauterized. Why: To prevent recurrent VF and reduce ICD shocks in high-risk patients. Evidence shows sustained benefit when arrhythmia-triggering substrate is eliminated. ahajournals.org+1

3) Left cardiac sympathetic denervation (LCSD) / stellate ganglion block.
What happens: Temporary percutaneous block or surgical denervation reduces sympathetic drive to the heart. Why: As an adjunct in refractory electrical storm when other measures fail. ahajournals.org+1

4) Emergency temporary pacing (selected cases).
What happens: A temporary pacer increases heart rate to suppress arrhythmias while definitive therapy is arranged. Why: As a bridge in unstable patients with recurrent events. guardheart.ern-net.eu

5) Comprehensive electrophysiology study and mapping.
What happens: Invasive testing under expert care to assess substrate and guide ablation decisions. Why: To localize arrhythmia sources and tailor therapy. guardheart.ern-net.eu

When to see a doctor (or go to the ER)

Seek urgent care if you faint, feel your heart racing with dizziness, have chest pain, or develop a high fever that does not respond to medicines—especially if you already have Brugada syndrome. See your cardiologist quickly if you receive an ICD shock, start a new medicine, plan surgery or dental work, or if a close relative is newly diagnosed. Family members of someone with Brugada should ask about screening even if they feel well. guardheart.ern-net.eu+1

Things to eat and to avoid

A heart-healthy eating pattern supports general cardiovascular health, but it does not replace proven Brugada care. Focus on whole foods, steady hydration, and avoiding heavy alcohol. www.heart.org+1

What to eat: vegetables; fruits; whole grains; legumes; nuts/seeds; fish in moderation; lean poultry; low-fat dairy if used; olive/plant oils; plenty of water for hydration, especially during fever. www.heart.org

What to avoid or limit: binge alcohol; energy drinks/stimulant supplements; highly processed foods; trans fats; excess saturated fat; very high-sodium meals; large doses of over-the-counter decongestants without checking safety lists; “heart health” supplement mixes with big claims; smoking/vaping (not food, but key lifestyle risk); extreme caffeine loads if you notice palpitations. Always check drug-safety lists for any product with active drugs. brugadadrugs.org+1

Frequently asked questions

1) Can Brugada be cured?
No. It is a lifelong electrical condition. Risk can be controlled with ICDs, ablation in selected patients, trigger avoidance, and emergency fever treatment. guardheart.ern-net.eu

2) Do all patients need an ICD?
No. ICDs are for people at highest risk (e.g., prior cardiac arrest, documented VT/VF, or specific high-risk features after specialist assessment). guardheart.ern-net.eu

3) Why is fever dangerous?
Heat further weakens sodium channels, exposing the ECG pattern and raising arrhythmia risk—treat fever fast. PMC

4) Are there safe pain/fever medicines?
Yes—use standard antipyretics (e.g., acetaminophen). Always check a Brugada drug list before new medicines. brugadadrugs.org+1

5) Can I exercise?
Most people can do regular exercise. Stop if you get dizzy or faint and get checked, and seek advice before competitive sports if you’ve had symptoms. guardheart.ern-net.eu

6) Is there a “Brugada diet”?
No. Eat a heart-healthy pattern and stay hydrated; diet does not replace proven Brugada treatments. www.heart.org

7) Do supplements help?
There is no supplement proven to prevent Brugada arrhythmias; some (like high-dose fish oil) may even raise AF risk in some groups. jacc.org+1

8) Which drugs should I avoid?
Check a Brugada-specific drug list and show it to every prescriber/pharmacist. brugadadrugs.org

9) Can ablation replace an ICD?
Ablation can reduce recurrent arrhythmias and shocks in selected high-risk patients, but ICD decisions remain individualized with your electrophysiologist. ahajournals.org

10) What about pregnancy?
Most pregnancies are safe; share your diagnosis early so teams can pick safe drugs and monitor as needed. PubMed

11) Do children get Brugada?
Yes. Fever control is vital, and families should discuss screening with a specialist team. PMC

12) Can common cold medicines be dangerous?
Some can. Many combine active drugs; always check the Brugada list or ask your pharmacist/cardiologist. brugadadrugs.org

13) Is alcohol safe?
Avoid binge drinking; it can trigger arrhythmias. guardheart.ern-net.eu

14) What if I live far from a heart center?
