The need for a simple, non-invasive technique for evaluating ventricular function in patients with acute myocardial infarction is apparent. The usefulness of the easily determined left ventricular ejection time as an indication of stroke index in patients with stable circulatory systems has been documented by other investigators. The present study was designed to determine whether such a relationship also exists in patients with acute myocardial infarction.
The left ventricular ejection time was determined simultaneously with cardiac output (indicator dilution) and heart rate in 18 patients with acute myocardial infarction. The ejection time was measured in 11 of the patients from
