Acute myocardial ischemia can cause ventricular tachycardia (VT) in patients with structurally normal heart. Contrary to the fact that in patients with chronic myocardial scarring the ventricular tachycardia is monomorphic, in patients with acute ischemia the ventricular tachycardia is polymorphic and is reversible with coronary revascularization.We are reporting a 40 year old male who presente...
BACKGROUND Mutations in the cardiac ryanodine receptor gene (RyR2) underlie catecholaminergic polymorphic ventricular tachycardia (CPVT), an inherited arrhythmogenic disease occurring in the structurally intact heart. The proportion of patients with CPVT carrying RyR2 mutations is unknown, and the clinical features of RyR2-CPVT as compared with nongenotyped CPVT are undefined. METHODS AND RES...
Çongenital long-QT syndrome (LQTS) is an inherited disorder that presents with syncope, polymorphic ventricular tachycardia, torsade de pointes and sudden death. The incidence rate of LQTS is 1 to 2 per 100000 and mainly involves children and young individuals. Because of familial and genetic underling and predisposing factors for life threatening arrhythmias in patients, diagnosis and treatm...
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...
An 82-year-old woman with a previous history of inferior myocardial infarction was admitted to our hospital with the complaint of syncope. She had received hemodialysis for chronic renal failure and an oral administration of pilsicainide (50 mg daily) for prevention of paroxysmal atrial fibrillation. The ECG showed repetitive polymorphic ventricular tachycardia (VT) initiating from the same pre...
An asymptomatic 5-year-old girl presented with bradycardia during a routine well-child visit. Further evaluation revealed profound sinus bradycardia, exercise-induced bidirectional ventricular tachycardia, and supraventricular tachycardia. An echocardiogram showed heavy trabeculations in the left ventricular myocardium. This patient's presentation suggested catecholaminergic polymorphic ventric...
Since the earliest description of cardiac involvement in scleroderma by Heine (1926) and the subsequent emphasis on scleroderma heart disease by Weiss et al. (I943), a number of publications concerning the clinical features and pathological changes in this disease have appeared. The electrocardiographic abnormalities with or without clinical evidence of cardiac involvement in scleroderma have b...
