The Universal ECG uses the Louvaine analysis program. In 1991, clinical researchers evaluated nine popular ECG algorithms compared to eight cardiologists relative to a standardized database of ECG tracings1. The Louvaine algorithm had the best total accuracy of all the algorithms (77.3%) evaluated. It was also the best in correctly diagnosing Myocardial Infarction (82.1%) and the second best in diagnosing Ventricular Hypertrophy, which were both better than the respective combined scores of the eight cardiologists.
