An implantable medical device, such as a pacemaker, stores diagnostic information pertaining to a variety of events detected by the medical device for subsequent transmission to an external programmer device. The external programmer device displays graphical representations of the diagnostic information under the control of a physician operating the programmer device. In one example, wherein the implantable medical device is a pacemaker coupled to the heart of a patient, the pacemaker senses events occurring within the heart during a refractory period following generation of a stimulation signal, stores diagnostic information pertaining to those events as "event records" within the pacemaker, and ultimately transmits the event records to the external programmer device for display thereon in various graphical formats. The events occurring during the refractory period include events such as a P-wave detected during a relative post-ventricular atrial refractory period not followed by a ventricular pulse or an R-wave detected during a relative ventricular refractory period or a P-wave detected during an atrial refractory period during an AV/PV interval.

[ What is claimed is:] [1.] A system for detecting and displaying information received from an implantable medical device capable of generating a stimulation signal within tissue connected to the implantable medical device and capable of sensing electrical events occurring within the tissue, said system comprising:means for receiving signals from the implantable medical device representative of events detected during a refractory period following generation of a stimulation signal and signals representative of events detected outside of the refractory period; andmeans for graphically displaying a first set of icons representative of the events detected during the refractory period and a second set of icons representative of the events detected outside of the refractory period, with the first and second sets of icons being distinct from one another.
