Overview
Brugada syndrome is a disease that can cause an abnormal rhythm in your heart’s lower chambers (ventricles). This irregular heart rhythm, ventricular fibrillation (v-fib), prevents your heart from pumping blood to your brain. When this happens, you faint.
V-fib can lead to sudden cardiac death. This often happens while you’re at rest or asleep. Out of all the sudden cardiac deaths that happen, researchers blame Brugada syndrome for 4% of them.
Brugada syndrome is rare. About 3 to 5 people in 10,000 have the condition.
