Noninvasive electrophysiologic study using standard permanent pacemakers in patients with spontaneous sustained ventricular tachycardia or ventricular fibrillation. 1987

A I Cohen, and R D Fletcher, and M H Wish, and F C Miller, and A Del Negro

Permanent pacemakers capable of noninvasive electrophysiologic testing were used to study and treat 26 patients with spontaneous sustained ventricular tachycardia (VT) or fibrillation (VF). One hundred nine episodes of sustained VT or VF were induced in these patients. In 8 patients spontaneous VT was reverted by noninvasive means. Drug changes based on noninvasive testing were made in 12 patients. In the 1- to 67-month follow-up period, drug therapy based on noninvasive electrophysiologic testing was predictive of outcome in patients with spontaneous arrhythmias. Thus, noninvasive electrophysiologic testing using permanent pacemakers is a useful method for studying and treating patients with recurrent sustained ventricular arrhythmias.

D013610 Tachycardia Abnormally rapid heartbeat, usually with a HEART RATE above 100 beats per minute for adults. Tachycardia accompanied by disturbance in the cardiac depolarization (cardiac arrhythmia) is called tachyarrhythmia. Tachyarrhythmia,Tachyarrhythmias,Tachycardias
D014693 Ventricular Fibrillation A potentially lethal cardiac arrhythmia that is characterized by uncoordinated extremely rapid firing of electrical impulses (400-600/min) in HEART VENTRICLES. Such asynchronous ventricular quivering or fibrillation prevents any effective cardiac output and results in unconsciousness (SYNCOPE). It is one of the major electrocardiographic patterns seen with CARDIAC ARREST. Fibrillation, Ventricular,Fibrillations, Ventricular,Ventricular Fibrillations
