| Abstract: | Based on combination method of edge enhancing, matched filtering and area thresholding(CEMA) a method of extracting pacemaker impulses from body surface ECG was presented. The feasibility of the proposed method was examined with MIT ECG database and simulating signals. The sensitivity and speciality were found to be 99.85% and 99.93% respectively. The method might be used to extract real time pacemaker impulses from ambulatory ECG recording system. |
