M-mode echocardiography in left bundle branch block: significance of frontal plane QRS axis.

abstract：BACKGROUND:Previous research suggests that after coronary artery bypass graft (CABG) surgery, women fare worse than men. This study investigates sex differences in depression during recovery from CABG surgery. METHODS:We followed 137 patients (72 men, 65 women) undergoing elective isolated first CABG surgery between J...
