Data are n (%) or median [25th–75th percentile]
SVA supraventricular arrhythmia; E/e′ ratio ratio of transmitral Doppler early (E) filling velocity to tissue Doppler early diastolic mitral annular velocity; RA right atria; LA left atria; LV left ventricle; RV right ventricle, RV dilatation was defined as end-diastolic area ratio >0.6; TAPSE tricuspid annular plane systolic excursion
^aOne patient had internal pacing
^bTwo patients were excluded from this analysis because of a poor echogenicity
