Overview

Ischemic heart disease is a common cause of ventricular tachycardia. Other causes of ventricular tachycardia are illicit drug use such as cocaine and methamphetamine, structural heart diseases including congenital heart diseases and inherited channelopathies. In addition, drugs that prolong the QT interval and electrolyte disturbances such as hypokalemia, hypomagnesemia, and hypocalcemia can also predispose to ventricular tachycardia.

Causes

Life Threatening Causes

Life-threatening causes include conditions which may result in death or permanent disability within 24 hours if left untreated. They are mainly due to acute conditions that promote rapid dysfunction of automaticity and include:
