Indicator of Myocardial Ischemia Based on the Mean Power of ECG Low Frequency Content: Comparison with ST Segment Trend


In order to cause myocardial ischemia, the left anterior descending coronary artery was occluded and released two times in twelve dogs. The occlusion release times and the ECG were recorded. Spectral content in the range of 1 to 10 Hz was obtained by means of a digital filter. After filtering, the mean power was determined and plotted in normalized trend… (More)
