Idiopathic sustained left ventricular tachycardia: clinical and electrophysiologic characteristics.
Electrophysiologic studies were performed in 16 patients 11 to 45 years old (mean 33 years) with idiopathic sustained (lasting more than 5 min) ventricular tachycardia (VT) originating from the left ventricle. Endocardial mapping during VT showed that the earliest site of activation was at the apical inferior portion of the left ventricle in 14 patients whose QRS morphology during VT showed a r...

متن کاملUnifying mechanism of sustained idiopathic atrial and ventricular annular tachycardia.
BACKGROUND Based on the current understanding of cardiac conduction system development and the observation that arrhythmogenic foci can originate in areas near the atrioventricular annuli, we hypothesized that focal annular tachycardias, whether atrial or ventricular, share a common mechanism. We, therefore, prospectively evaluated this hypothesis in patients with sustained atrial and ventricul...
متن کاملRight ventricular tachycardia: clinical and electrophysiologic characteristics.
This report describes the clinical and electrophysiologic characteristics of 30 patients without myocardial disease who had ventricular tachycardia with the morphologic characteristics of left bundle branch block and inferior axis. The tachycardias were nonsustained in 24 patients, sustained (greater than 30 sec) in six patients, and provocable by exercise in 14 of 23 patients undergoing a stan...
