Abstract:
A method of identifying a portion of a waveform representing a physiological event, the method comprising:identifying a first R wave in an ECG; determining a first interval in the waveform between a first point offset a predetermined amount ahead of the first R wave and a second point offset a predetermined amount behind the first R wave; identifying the highest peak of the waveform in the first interval; identifying a second R wave in the ECG, the second R wave positioned ahead of the first R wave; establishing a second interval that extends from the second point to a third point, the third point positioned ahead of the second point at a distance equal to a first percentage of the interval from the second point to a predetermined amount behind the second R wave; identifying the highest peak in the waveform in the second interval; establishing a third interval that extends from the highest peak in the first interval to a fourth point positioned at a distance ahead of the highest peak in the first interval equal to a second percentage of the distance between the highest peak in the first interval and the highest peak in the second interval; and identifying the highest peak in the waveform in the third interval.
