Claim 4:
5. The method of claim 3, wherein the comparing comprises:
identifying positive and negative peaks in the IQRS and gQRS signals;
determining abnormal positive peaks in the IQRS signal by counting the number of positive peaks in the IQRS signal within ±M msec of each positive peak in the gQRS signal while excluding the nearest or greatest amplitude IQRS peak within ±M msec of each positive peak in the gQRS signal;
determining abnormal negative peaks in the IQRS signal by counting the number of negative peaks in the IQRS signal within ±M msec of each negative peak in the gQRS signal while excluding the nearest or least amplitude IQRS peak within ±M msec of each negative peak in the gQRS signal; and
determining the QRSp score as the total of the abnormal positive peaks and the abnormal negative peaks in the IQRS signal.
