Overview
Catecholaminergic polymorphic ventricular tachycardia (CPVT) was first described by Reid et al in 1975. It was described as a familial cardiac arrhythmia that occurs in patients with structurally normal heart and causes exercise or emotion triggered syncope and sudden death with a distinguishing pattern of ventricular and supraventricular arrhythmias. In 2001, cardiac Ryanodine Receptor gene (RyR2) mutations were first implicated in the pathogenesis of catecholaminergic polymorphic ventricular tachycardia (CPVT). Subsequent experimental studies demonstrated that the abnormal calcium release from the sarcoplasmic reticulum caused arrhythmias mediated by delayed afterdepolarizations and triggered activity.
Historical Perspective
- Catecholaminergic polymorphic ventricular tachycardia (CPVT) was first described by Reid et al in 1975, followed by Coumel et al in 1978.[1]
- CPVT was described as a familial cardiac arrhythmia that occurs in patients with structurally normal heart and causes exercise or emotion triggered syncope and sudden death with a distinguishing pattern of ventricular and supraventricular arrhythmias.
- In 2001, Cardiac Ryanodine Receptor Gene (RyR2) mutations were first implicated in the pathogenesis of catecholaminergic polymorphic ventricular tachycardia (CPVT).[2]
- In 1995 and 2002, the clinical studies by Leenhardt et al and Priori et al, respectively, have contributed to the understanding of the natural history of CPVT.[3][4]
- In 2004, studies showed that RyR2 mutations reduced the threshold for Store-Overload-Induced Ca2+ Release (SOICR) and increased the tendency for triggered arrhythmia. Thus it appeared evident that catecholaminergic polymorphic ventricular tachycardia was caused by uncontrolled Ca2+ release from the sarcoplasmic reticulum.[5]
- In 2006, subsequent experimental studies demonstrated that the abnormal calcium release caused arrhythmias mediated by delayed afterdepolarizations and triggered activity.[6]
