Overview

Common causes of ventricular tachycardia include ischemic heart disease, illicit drugs (cocaine and methamphetamine), structural heart disease (including congenital heart diseases such as tetralogy of Fallot), inherited channelopathies, drug toxicity (digoxin, drugs that prolong the QT interval) and electrolyte disturbances (such as hypokalemia, hypomagnesemia, and hypocalcemia).

Causes

Common Causes

Across All Ages

• Congestive heart failure
• Hypokalemia
• Hypomagnesemia
• STEMI

Among Patients Under 35 Years of Age

• Arrhythmogenic right ventricular dysplasia
• Hypertrophic cardiomyopathy
• Long QT syndrome
• Myocarditis
• Short QT syndrome
• Short QT syndrome type 1
• Short QT syndrome type 2
• Short QT syndrome type 3
• Short QT syndrome type 4
• Short QT syndrome type 5
