Abstract: The computation and characteristics of two new representations of single lead electrocardiogram data, both based upon the analytic signal corresponding to the waveform, are presented. The first method, employing a complex plane plot of the analytic signal, emphasizes waveform shape independently of time base; the second, a time-frequency representation using the Wigner-Ville distribution, appears to highlight instantaneous frequency variation within the waveform. Both are potentially useful when the patterns are displayed using contour plots, and a specific computerised pattern recognition technique is suggested and some results presented.
