Journal ArticleDOI
Recurrent sustained ventricular tachycardia. 1. Mechanisms.
TL;DR: It is concluded that endocardial ventricular mapping demonstrates the limitations of the surface electrocardiogram in localizing the site of origin of ventricular tachycardia.
Journal ArticleDOI
Recurrent sustained ventricular tachycardia. 2. Endocardial mapping.
TL;DR: It is concluded that endocardial ventricular mapping demonstrates the limitations of the surface electrocardiogram in localizing the site of origin of ventricular tachycardia.
Journal ArticleDOI
Electrocardiographic left atrial enlargement. Electrophysiologic, echocardiographic and hemodynamic correlates.
TL;DR: The electrocardiographic pattern appears to represent an interatrial conduction defect that can be produced by a variety of factors and is unrelated to either left atrial pressure or volume overload.
Journal ArticleDOI
Intracardiac electrophysiologic studies as a method for the optimization of drug therapy in chronic ventricular arrhythmia.
Journal ArticleDOI
