Abstract
Idiopathic left ventricular tachycardia is known to be responsive to verapamil in many cases. However, the role of other calcium‐channel blockers, such as diltiazem, in treating this specific type of ventricular tachycardia is unknown. We report a case of idiopathic left ventricular tachycardia in a patient with a structurally normal heart, which was terminated and suppressed in the electrophysiology laboratory by a single dose of diltiazem intravenously, and was subsequently suppressed long‐term with sustained‐release diltiazem. Our finding suggests that idiopathic left ventricular tachycardia may be managed effectively with diltiazem in both the acute and chronic settings.
Keywords: calcium‐channel blockers, diltiazem, ventricular tachycardia
