Abstract
A system for analyzing an ECG signal is provided. The system comprises an interface that receives an ECG waveform associated with heart beat cycle of a patient. The system includes signal processor that determines a first isoelectric portion lying between a T-wave of a first heart beat cycle and a P-wave of a successive heart beat cycle, and a second isoelectric portion lying between a P-wave and a QRS complex of the first heart beat cycle. The signal processor determines a stability measure for each of said first and second portions and adaptively selects the first or the second portion as a baseline for the first heart beat cycle based on the stability measures. The signal processor determines a point of reference on an ST segment associated with the first heart beat cycle and evaluates a deviation of the point of reference on the ST segment from the selected baseline.
