Data are mean (SD).

*p = 0.05; **p = 0.03; ***p = 0.002.

AV, atrioventricular; CI, cardiac index; LBBB, left bundle branch block; LVEDV, left ventricular end diastolic volume; LVEF, left ventricular ejection fraction; M:V, mass to volume ratio; PAP, mean pulmonary artery pressure; P:ESV, pressure end systolic volume ratio; PCWP, pulmonary capillary wedge pressure.
