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.

Recognition of noisy peaks in ECG waveforms.

A new method for recognizing noisy peaks in ECG waveforms is presented. This method is based on the principle that most noisy peaks in ECG waveforms appear as pairs of adjacent peaks which satisfy certain criteria. These pairs are called "noisy peak pairs" in this paper. The above principle was originally based on observation and was subsequently checked and found to be correct utilizing a standard ECG library, namely, the CSE library. With this method and using that library, 84.8% on the average of all peaks in every lead were recognized as noisy. This method is useful when employed as a step in the process of recognizing the real peaks in ECG waveforms.
