WebDetails. Q waves do not always indicate infarction. Must distinguish normal septal q waves from pathologic Q waves: Normal septal q wave: <0.04s, low amplitude. Abnormal septal q wave: >0.04s in I OR in II, III, AND aVF OR … WebNeither the intermittence of Q wave in V2 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.
