Myopericarditis – a rare cause of bidirectional ventricular tachycardia

Bidirectional Ventricular Tachycardia: A Hallmark of Catecholaminergic Polymorphic Ventricular Tachycardia

Catecholaminergic polymorphic ventricular tachycardia is a familial cardiac arrhythmia that is related to RYR2 or CASQ2 gene mutation. It occurs in patients with structurally normal heart and causes exercise-emotion triggered syncope and sudden cardiac death. We present a 13 year-old girl with recurrent episodes of exercise-related syncope and prior history of sudden death in a first degree rel...

Catecholaminergic polymorphic ventricular tachycardia: a rare cause of recurrent syncope

Catecholaminergic polymorphic ventricular tachycardia (CPVT) is an inherited arrhythmia characterized by adrenergically induced polymorphic or bidirectional ventricular tachycardia (VT). Although a rare disease, its recognition is important because of its high mortality rate when left untreated. We report an index case of a 32-year-old woman who presented with recurrent syncope. The diagnosis w...

Bidirectional ventricular tachycardia?

A 65-year-old woman was admitted to the hospital because of a syncopal episode with documented transient complete atrioventricular block. A DDD pacemaker was implanted. Post implantation, the patient was diagnosed with bidirectional ventricular tachycardia. Analysis of the arrhythmia and differential diagnosis is performed.

A rare cause of tachycardia.

An anomalous aortic origin of the coronary arteries is rare, with a reported incidence of 0.3--1.3%. An anomalous left coronary artery from the right sinus with an interarterial course has a prevalence of 0.17% and is associated with a high risk of sudden cardiac death during or after strenuous exertion. We present the case of a 45-year-old woman with no relevant medical history referred for ca...
