Brugada syndrome is a rare and serious heart rhythm disorder.
Many people who have Brugada syndrome don’t have any symptoms, and so they’re unaware of their condition.
A telltale abnormality — called a type 1 Brugada ECG pattern — is detected by an electrocardiogram (ECG) test.
Brugada syndrome is much more common in men than women and can occur at any age but typically from 30 years old and onwards.
Each beat of your heart is triggered by an electrical impulse generated by special cells in the right upper chamber of your heart.
Tiny pores, called channels, on each of these cells direct this electrical activity, which makes your heart beat.
In Brugada syndrome, a defect in these channels can cause your heart to beat abnormally and spin electrically out of control in an abnormally fast and dangerous rhythm (ventricular fibrillation).
As a result, your heart doesn’t pump effectively and not enough blood travels to the rest of your body.
This will cause fainting if that rhythm lasts for only a short time or sudden cardiac death if the heart remains in that bad rhythm.
Cause
Family history- (parent to child)
Caused by abnormal heart rhythm (the way electrical signals pass through in ones heart) from the lower chambers of the heart (ventricular arrhythmias)
