Does verapamil treat idiopathic fascicular left ventricular tachycardia in pediatric patients?
Idiopathic fascicular left ventricular tachycardia in pediatric patients is an uncommon arrhythmia that uniquely responds to verapamil compared to other wide-complex arrhythmias.
IMAGE: Electrocardiogram demonstrating idiopathic fascicular left ventricular tachycardia. CASE SUMMARY: An 11-year-old boy with a history of tuberous sclerosis-related intractable epilepsy exhibited an idiopathic ventricular tachycardia that was resistant to multiple antiarrhythmic treatments, but was responsive to verapamil. We discuss the recognition and treatment of verapamil-sensitive fascicular left ventricular tachycardia. TAKE-HOME MESSAGES: Idiopathic fascicular left ventricular tachycardia in pediatric patients is an uncommon but recognizable arrhythmia. Its management differs from that of more commonly occurring pediatric wide-complex arrhythmias in that it readily responds to verapamil.

DeLong et al. (2026) conducted a case report in Idiopathic fascicular left ventricular tachycardia (n=1). Verapamil was evaluated. Verapamil successfully treated idiopathic fascicular left ventricular tachycardia in an 11-year-old boy whose arrhythmia was resistant to multiple other antiarrhythmic treatments.
