An external diagnostic/programming device is disclosed which includes means for both displaying intracardiac electrical signals sensed and telemetered from an implantable pacemaker in real-time, and for storing the intracardiac electrical signals for subsequent retrieval and analysis. The subsequent analysis selectively includes processing means for processing the signals off-line (i.e., not in real-time), using various signal processing strategies, such as digital filtering and frequency domain spectral analysis. The off-line signals may also be recursively processed in order to enhance the detection of a particular physiologic phenomena manifested by, but not readily discerned within, the unprocessed real-time signals.
