Techniques are provided for controlling the recording of intracardiac electrograms (IEGMs) within an implantable medical device such as a pacemaker, wherein the device is capable of recording different channels of IEGMs in response to different diagnostic triggers. Exemplary triggers include pacemaker-mediated tachycardia; atrial tachycardia, atrial fibrillation, ventricular tachycardia, etc. In one example, the device stores, for each diagnostic trigger, a physician selection of particular IEGMs to be recorded for subsequent review. Then, whenever a trigger is detected, the device senses and records only the particular IEGMs that had been selected by the physician for that particular trigger. The IEGMs are eventually transmitted to an external programmer for review. In this manner, the physician can specify particular IEGMs to be stored in response to particular diagnostic triggers, thereby providing considerable diagnostic flexibility, while also conserving memory. Triggers can be classified as atrial-related or ventricular-related, with appropriate IEGMs stored. Pre-trigger IEGM storage can also be accommodated.
