Values are mean±standard deviation. bpm indicates beats per minute; HR, heart rate; IVS, intraventricular septum; LA, left atrial; LV, left ventricular; LVEF, left ventricular ejection fraction; RA, right atrial; RV, right ventricular; SDB, sleep‐disordered breathing; TAPSE, tricuspid annular plane systolic excursion; TDI, tissue Doppler imaging.
