Noninvasive electrocardiographic mapping to guide ablation of outflow tract ventricular arrhythmias

摘要

BackgroundLocalizing the origin of outflow tract ventricular tachycardias (OTVT) is hindered by lack of accuracy of electrocardiographic (ECG) algorithms and infrequent spontaneous premature ventricular complexes (PVCs) during electrophysiological studies.
