Treatment of catecholaminergic polymorphic ventricular tachycardia in mice using novel RyR2-modifying drugs

摘要

Rationale Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a potentially lethal arrhythmic disorder caused by mutations in the type-2 ryanodine receptor (RyR2). Mutant RyR2 cause abnormal Ca2+ leak from the sarcoplasmic reticulum (SR), which is associated with the development of arrhythmias.
