A new algorithm applied to the analysis of the electrocardiogram of an isolated rat heart

摘要

A new correlation algorithm has been developed to analyze an isolated rat heart electrocardiogram (ECG). This is done as follows: The original ECG signal is altered into a wave having three levels +1, -1 or zero depending on whether the signal is above zero, below zero or approximately zero respectively. This reduces the computation time and storage memory considerably, by altering the multiplications into simple additions or subtractions when the signal is positive or negative and no operation when the signal is zero. The algorithm has been developed, implemented and tested using a Pentium PC.
