Claim 13:
14. The method of claim 12, wherein the first time interval comprises an earlier time interval and a subsequent time interval, the subsequent time interval occurring after the earlier time interval, and
wherein comparing the first ECG signals in accordance with the selection criterion further comprises:
identifying amplitudes of peaks in segments of the first ECG signals detected during the earlier time interval;
identifying amplitudes of peaks in segments of the first ECG signals detected during the subsequent time interval;
determining ratios corresponding to the amplitudes of the peaks in the segments of the first ECG signals detected during the earlier time interval and the amplitudes of the peaks in the segments of the first ECG signals detected during the subsequent time interval; and
comparing the ratios.
