Abstract

This is a computer program for determining whether a regularly spaced train of pulses is present in the previously found pulse-like bumps or waves of an electrocardiographic signal. The program is illustrated in detail on the figure.

Routine For Identification of Regular Pulse Trains

This is a computer program for determining whether a regularly spaced train of pulses is present in the previously found pulse-like bumps or waves of an electrocardiographic signal. The program is illustrated in detail on the figure.

The program is based on an algorithm, which is provided to determine whether or not a regularly spaced train of pulse-waves exists, giving the locations of all pulse-like bumps found. It should be understood that a regularly spaced train of pulse-waves, includes a train of pulse-waves which are almost or substantially uniformly spaced. in accordance with the degree of tolerance specified in the algorithm. If the previously located and tentatively identified pulse-wave train comprising pulse-like bumps, which may include real pulse- waves, noise, fibrillations, etc., is determined by the algorithm to comprise therein a regular pulse-wave train, then, further special processing and analysis has to be undertaken. If, on the other hand, it is determined by the algorithm that the previously located and tentatively identified pulse-wave train is not regular, then no clear inference can be drawn therefrom, since the determined irregularity may be based upon the fact that some of the previously located pulse-waves are in fact noise, atrial fibrillation waves, etc. Alternatively, the determined irregularity may, in fact, be due to some cardiac condition.

The algorithm assumes that pulse-waves...
