Why the study?
Does the appearance of new Q waves after aortocoronary bypass surgery correlate with deterioration in ventricular wall motion?
Does the appearance of new Q waves after aortocoronary bypass surgery correlate with deterioration in ventricular wall motion?
New Q waves appearing after aortocoronary bypass surgery correlate strongly with localized deterioration in ventricular wall motion, indicating perioperative myocardial infarction.
No takes yet. Share an insight, caveat, or question.
New Q waves post-bypass may indicate perioperative MI; supports ECG correlation but leaves open validation in larger cohorts.
Sternberg et al. (1975) studied this question.
