Catecholaminergic polymorphic ventricular tachycardia (CPVT) is an inherited arrhythmogenic disease that can cause syncope during exercise or acute emotion. Some individuals may also experience palpitations and dizziness. Symptoms are caused by fast ventricular tachycardia. The mean age of onset of symptoms is between age seven and twelve years.

Spontaneous recovery may occur when these arrhythmias self-terminate. Ventricular tachycardia may degenerate into ventricular fibrillation and cause sudden death. Sudden death during exercise or while experiencing acute emotions may be the first manifestation of the disorder in previously asymptomatic individuals.

The estimated prevalence of CPVT is 1:10,000.

CPVT is most commonly inherited in an autosomal dominant pattern. CASQ2-related CPVT and TDRN-related CPVT are autosomal recessive.
