The QRS–right ventricular apex interval as a cut-off value to differentiate the origin of outflow tract premature ventricular complexes

Background Many electrocardiography (ECG) criteria have been proposed for the localization of outflow tract premature ventricular contractions (PVCs); however, in some cases, it is difficult to accurately localize the origin of PVCs using the surface ECG. The authors aimed to study the QRS–right ven...
