Overview

Catecholaminergic polymorphic ventricular tachycardia is caused by mutations in genes encoding channel proteins that regulate the cardiac electrical function, resulting in inappropriate calcium leak from the sarcoplasmic reticulum during electrical diastole and thus leading to triggered arrhythmias, in the absence of structural cardiac abnormalities. CPVT is thus an inherited disorder and may have both autosomal dominant and autosomal recessive pattern of inheritance. Genes associated with CPVT include RYR2, CASQ2, CALM1 and TRDN.
