摘要

(A) Ventricular arrhythmias (VAs) originating around the right pulmonary sinus (PRS) in different types of inferior axis ECG. (B) Electrocardiographic localization of VAs with inferior axis and LBBB pattern; G1, case group; G2, non-RVOT control group; G3, RVOT control group. (C) Hypothesis of the longer R-wave duration during PRS-VAs in lead-V1. (D) The electric axis of the control and case group during sinus rhythm. Fw., free wall; LBBB, left bundle branch block; PA, pulmonary artery; RVOT/LVOT, right/left ventricular outflow tract; Sep., septum; TA/MA, tricuspid/mitral annulus.
