ABSTRACT:
An improved electrocardiac monitoring device is disclosed in which the sampling period utilized to sample the ECG signal is varied dynamically. Specifically, during rapidly varying portions of the ECG signal, the sampling rate is high. As the rate of change of the ECG signal decreases, the sampling rate is slowed so that only the minimum number of samples are taken to accurately reconstruct the analog ECG signal. The sampling period to be used is determined from the relative positions in time between a predetermined portion of the ECG signal and the portion of the ECG signal being sampled.
