Significance of new Q waves after bypass grafting: correlations between graft patency, ventriculogram, and surgical venting technique.

abstract：:A large series of 306 patients with ischemic heart disease was studied with automated systolic time intervals and left ventricular ejection fraction as determined by the angiocardiographic method. It was found the pre-ejection period, left ventricular ejection time, delta values, and PEP/LVET ratio all were related to...
