  • Abstract
  • Look Inside

In order to evaluate the clinical significance of left ventricular systolic time interval (STI) and A wave ratio, 70 cases of coronary artery disease were studied by coronary arteriography and left ven-triculography.

1. The Ill vessel disease group had a signifi-cantly longer preelection period (PEP), smaller ET/PEP ratio than the other vessel disease group.

2. The similiar findings were obtained in group with asyncrgy as compared to group with normal left ventricular wall motion.

3. The group with old myocardial infarction had a longer PEP, smaller ET/PEP ratio than the group with angina pectoris, but not significant.
