VENTRICULAR PARASYSTOLIC TACHYCARDIA

Ventricular Parasystolic Tachycardia.

Ventricular tachycardia like ventricular parasystole is rarely observed in the absence of cardiac disease (Massie and Walsh, 1960; Scherf and Bornemann, 1961), though several cases of functional ventricular tachycardia without demonstrable heart disease have been reported by Hair, Eagan, and Orgain (1962) and others. Parasystole consists of simultaneous activity of two independent impulse-formi...

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...

Papillary Muscle Ventricular Tachycardia Masquerading as Bidirectional Ventricular Tachycardia

Introduction: Bidirectional ventricular tachycardia (VT) is a rare type of VT that appears in digoxin toxicity and young patients with catecholaminergic polymorphic VT (CPVT). The occurrence of bidirectional VT originating from the papillary muscle has not been reported in the literature. Case Presentation: A 38-year-old female presented with long standing palpitation lasting several months. Pa...
