Answers are grounded in this paper and cite their sources.
Unipolar epicardial QRS waveforms, specifically the magnitude of the Q wave, can accurately predict underlying myocardial infarction in a canine model.
This canine study assesses the ability to predict whether the myocardium lying directly below epicardial recording sites is infarcted or normal. The results indicate that sufficient information is present in unipolar QRS waveforms to predict with 90 percent accuracy the state of the myocardium. A simplified classifier based only on the magnitude of the Q wave also provides sufficient information for reliable prediction.
