Overview

Reversible/preventible risk factors for ventricular tachycardia include electrolyte disturbances such as hypokalemia, digitalis toxicity, antiarrhythmic use, pulmonary artery catheter placement and illicit drug use such as cocaine. Irreversible causes include structural heart disease and inherited channelopathies.

Risk Factors

Reversible Risk Factors

• Antiarrhythmics
• Amphetamines
• Cocaine
• Droperidol
• Inotropes
• Phenothiazines
• Sympathomimetic agents

Irreversible Risk Factors

• Arrhythmogenic right ventricular dysplasia
• Channelopathies
• Hemochromatosis
• Long QT syndrome
• Rheumatoid arthritis
• Sarcoidosis
• Short QT syndrome
• Systemic lupus erythematosus
• Tetralogy of Fallot
