Sequence of occurrence of abnormal regional cardiac function, global pump function and electrocardiogram after brief ligation and reperfusion of a coronary artery.
The following results were obtained. During brief ligation of the coronary artery, a change in the cardiac wall motion appeared as the first abnormality of the CMG. Succeedingly, epicardial ECG changes were recognized, and lastly, changes of dP/dt appeared. After reperfusion of the coronary artery, dP/dt was quickly normalized, followed by restoration of ST elevation. Cardiac motion, measured by CMG, was the last abnormality to improve.
