Bottom-up approach to the ECG pattern-recognition problem

A bottom-up approach to the recognition problem in ECG waveforms is presented in the paper. This approach is based on the assumption that ECG waveforms are composite entities that can be decomposed into other simpler entities, these into other simpler ones etc., until peak patterns and segment patterns are obtained. The peak patterns and the segment patterns are considered primitive (nondecomposable) patterns. The recognition is achieved by first recognising the primitive patterns and then recognising the (higher) ECG patterns using a bottom-up procedure.
