The incidence of adverse events, including syncope, ventricular tachycardia and ventricular fibrillation at 40 years of age is about 80%,2 and between 20 and 30 years, the incidence of sudden cardiac death is 30 to 50%.3 Currently, there are two known genetic mutations in CPVT, namely, RyR2 and CASQ2.4 These two ion channels mediate the transportation of calcium ions from the sarcoplasmic reticulum into the cytoplasm. Here, RYR2 is linked to ventricular fibrillation.
