BASIC STUDY ON REAL-TIME AMBULATORY ELECTROCARDIOGRAM. LOGICS FOR QRS COMPLEX DETECTION AND CLASSIFICATION.

The Ambulatory electrocardiogram is a very important clinical tool. However, its analysis by high-speed scanner in general use requires a great deal of labor and its accuracy is as yet insufficient. It is suspected that there is not enough time to detect and cluster each QRS complex at high-speed playback. Consequently complicated transactions cannot be used. To settle these problems, the authors have tried to develop a real-time ambulatory ECG analyzer. Evidence is provided that four parameters, namely QRS area, trace length, area/height (index A), area/trace length (index B), can be employed for the detection and the classification of the QRS complex.
