Abstract
Computer-implemented methods, computer program products, and systems are disclosed for analyzing electrocardiogram (ECG) traces or other types of signals. In one aspect, a computer-implemented method of performing such an analysis on an ECG trace includes defining a match region within an ECG signal template comprising one cardiac cycle. The match region comprises a portion of the ECG signal template that is shorter than the entire template. The method also includes performing a similarity comparison analysis on an ECG trace. The similarity comparison analysis includes, for at least one cardiac cycle within the ECG trace, a comparison of the defined match region to a corresponding region of the cardiac cycle of the ECG trace to determine a degree of similarity between the defined match region and the corresponding region of the cardiac cycle of the ECG trace. The method also includes producing a results output based upon the similarity comparison analysis.
