Q wave duration of >40 ms. and a depth of the Q wave of >-0.2 mV were considered suggestive of inferior wall myocardial infarction. In addition, the deviation of the ST segment from the baseline by more than 1 mm and polarity of the T wave were also analyzed. Echocardiograms, cardiac catheterization and

intermittence of Q wave in V 2 on repeated ECGs nor the absence of septal Q waves was useful in distinguishing between those with and without coronary heart disease. Conclusions: This ECG pattern is a sign of prior myocardial infarction in only a minority of cases, and in the latter, infarction limited to the interventricular septum is exceptional.
