To enhance the ability to visualize P-waves in surface ECG data, an algorithm is presented in which the ECG data is selectively passed through first and second signal processing channels where one of the channels includes signal processing elements for enhancing P-waves and the other channel provides a delayed version of the original data. Upon detection of an atrial pace event, the filtered or filtered and amplified data is inserted into the data stream in place of the raw input signal for a predetermined time interval sufficiently long to ensure the occurrence of an atrial depolarization signal.
