A rate of Q wave regression was assessed in 72 patients with ischaemic heart disease, including 46 patients after the infarction of the inferior wall and 26 patients after anterior wall infarction. All patients were followed-up for two years. Complete regression of Q wave was noted in 19 patients (41.3%) after inferior wall infarction and in one patient (3.8%) after anterior wall myocardial infarction. Partial regression of Q wave was seen in 9 patients (19.6%) after inferior wall, and in 2 patients (7.6%) of patients with anterior wall myocardial infarction. It seems that the regression of Q wave in ECG does not improve prognosis in these patients. Six out of 10 deaths which occurred in the followed up group of patients involved those in whom no electrographic features of the past myocardial infarction were seen.
