What is fatal ventricular arrhythmia?
Ventricular arrhythmias are abnormal heart rhythms that make the lower chambers of your heart twitch instead of pump. This can limit or stop your heart from supplying blood to your body. While some of these arrhythmias are harmless and don’t cause symptoms, some can have serious — or even deadly — effects on your body.

Can ventricular arrhythmia be cured?
Ventricular Tachycardia (VT) in patients without structural heart disease.

It can occur in both the young and the old, and can be a benign, potentially treatable and curable condition …
