Electrophysiologic study, isoproterenol infusion, and serial treadmill exercise tests before
and after administration of propranolol, verapamil, lidocaine, and procainamide were done …

Background—Catecholaminergic polymorphic ventricular tachycardia (CPVT) is caused by
mutations in the cardiac ryanodine receptor (RyR2) or calsequestrin (Casq2) and can be …

Calcium antagonists have emerged as a new class of antiarrhythmic agents for the control of
certain supraventricular and ventricular arrhythmias. Electrophysiologically, these agents …

Discussion Early diagnosis of catecholaminergic polymorphic ventricular tachycardia is
imperative because most cases respond well to beta-blockers. Left untreated, the risk of …

Abstract In 37 (70%) of 53 patients with idiopathic ventricular tachycardia (VT), episodes
were mainly related to exercise (group 1). These patients were younger (33±14 vs 44±18 …

We analyzed the results of exercise testing performed in the absence of all antiarrhythmic
drugs in 11 case patients with newly documented polymorphic ventricular tachycardia in …

Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a highly malignant
inherited arrhythmogenic disorder. Type 1 CPVT (CPVT1) is caused by cardiac ryanodine …

To elucidate electrophysiologic mechanism of exercise-induced ventricular tachycardia (VT),
electrophysiologic studies were performed in 12 patients in whom sustained VT had …

Verapamil-sensitive ventricular tachycardia (VT) is a well-recognized clinical entity that
some authorities believe may result from triggered activity. Despite its uniform response to …

Catecholaminergic polymorphic ventricular tachycardia is a rare entity that can occur in
children without cardiac disease and with a normal QT interval. It may cause syncope …
