Abstract

A computing device includes a memory device, a communication module, an interface, a processor, a display controller, and an input device. The communication module wirelessly receives a stream of first electrogram waveforms (EGMs) from an implantable medical device (IMD). The interface receives a stream of second EGMs. The processor stores the first and second EGMs and retrieves the stored first and second EGMs. The display controller displays the first and second EGMs together when the first and second EGMs are received. The input device is configured to receive a selection command from a user. The processor retrieves a portion of at least one of the first and second stored EGMs in response to the selection command. The display controller displays the retrieved portion of the at least one of the first and second stored EGMs while the processor concurrently stores the streams of the first and second EGMs.
