Heart Rhythm Abnormalities

Types of Brugada Syndrome:

1. Type 1 Brugada Syndrome:
   • This is the most severe form.
   • The ECG pattern shows a “coved” ST-segment elevation.
   • Patients with Type 1 are at the highest risk of sudden cardiac arrest.
2. Type 2 Brugada Syndrome:
   • The ECG pattern shows a “saddleback” ST-segment elevation.
   • This form is less dangerous than Type 1 but still requires attention.
