An implantable cardiac device such as a pacemaker or an implantable cardioverter defibrillator (ICD) that stores a broad band electrogram signal in response to the detecting of a particular cardiac event. The system includes an external programmer which is capable of accessing the stored electrogram via a telemetry circuit so that the stored electrogram can be downloaded and reviewed on a display of the external programmer. The external programmer is also equipped with a digital filter emulator that is capable of emulating the filtering of the broad band electrogram signal that is being provided to the processor of the implanted cardiac device. The emulator therefore allows a treating physician to review an emulation of the waveform that the processor of the implanted cardiac device is seeing when the processor is initiating the delivery of therapeutic electrical stimulation to the heart.

[ What is claimed is:] [1.]1. A system for displaying cardiac signals, comprising:an implantable cardiac stimulation device having:means for receiving a cardiac signal;filtering means for filtering the cardiac signal with a first filter to produce a first signal and for filtering the cardiac signal with a second filter to produce a second signal, wherein the second filter is selected to highlight a characteristic feature of heart activity;control means for controlling the delivery of therapeutic electrical stimulation to the heart based, at least in part, on the second signal; andtransmitting means for transmitting the first signal; andan external programmer having:receiving means, telemetrically coupled to the transmitting means, for receiving the first signal;processing means for processing the first signal and generating an emulated version of the second signal; anddisplaying means for displaying at least one of the received first signal or the emulated version of the second signal.
