Data are presented as mean±SD. E/Ea ratio indicates ratio of transmitral early diastolic filling velocity to mitral annular early diastolic velocity; IVMD, difference between the aortic and pulmonary pre‐ejection intervals; IVST, interventricular septum thickness; LAVI, left atrial volume index; LVEDd, left ventricular end‐diastolic diameter; LVEF, left ventricular ejection fraction; LVESd, left ventricular end‐systolic diameter; RVAP, right ventricular apical pacing; RVOT, right ventricular outflow tract.
