Abnormalities in the atrial complex were recorded in the ECG of 53% (101 patients) of 190 patients during the course of acute myocardial infarction. In sixty-four patients who showed serial P wave changes, only thirty-five have had clinical evidence of left ventricular failure. In fifty-seven patients who developed left ventricular failure, twenty-two showed no P wave changes in the ECG. Serial P wave changes during acute myocardial infarction are not a valuable predictive tool for identifying patients who are at risk of developing left ventricular failure in the acute phase of myocardial infarction. Other electrocardiographic, echocardiografic or invasive methods should be considered for this purpose
