Claim 16:
17. The system of 16, wherein the processing unit is configured to compare the IQRS signal with the gQRS signal to detect the abnormal QRS peaks in the IQRS signal by: 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.
