Exercise ECG analysis and measurement using an expert system approach

The difficulties of computerized analysis and measurement of the ECG (electrocardiogram) during exercise testing are compounded by the increases in noise and signal complexity at higher workloads and heart rates. By incorporating a hybrid expert-system structure in the analysis approach, information from the serial exercise ECG records are submitted to statistical and heuristic decision-logic to improve the accuracy of detection and measurement algorithms. Thus, in a manner similar to an expert cardiologist, the ECG analysis utilizes findings from previous records to aid in its determinations during each current record as the exercise test progresses.<>
