P-wave electrical alternans is a beat to beat alternation in the morphology of the P-wave, the wave in an electrocardiogram corresponding to atrial depolarization. In this investigation, software to measure p-wave alternans was developed and then tested on simulated data and on real data previously recorded from human subjects. The software consists of C programs managed by shell scripts and contains several features to minimize user interaction in data processing. The software can also calculate a signal averaged P-wave, apply various filters, and find the P-wave duration.
