Combining structural and plausible methods for P and T wave recognition

A technique for the recognition of structures in an electrocardiogram (ECG) and its application to the case of P and T-wave detection are presented. The technique combines a structural approach to the detection and description of structures, based on their shape properties, with a method based on multiple-valued logic for plausible evaluation of their medical meaning. The possibility of visualizing both the shapes of the structures and the reasoning process allow a human user to understand and control the recognition process. The method is general enough to be applied to the recognition and classification of the different patterns in the ECG.<
