1. A method comprising: receiving cardiac electrogram (EGM) signal data from an implantable medical device (IMD), the EGM signal data including a plurality of detected cardiac episodes, each of the plurality of cardiac episodes classified by the IMD as at least one of a ventricular tachycardia/ventricular fibrillation (VT/VF) episode, a supraventricular tachycardia (SVT) episode, a ventricular tachycardia non-sustained (VTNS) episode, an atrial tachycardia/atrial fibrillation (AT/AF) episode, a monitored VT episode, or a ventricular oversensing (VOS) episode; conducting a retrospective analysis of each of the plurality of cardiac episodes, the retrospective analysis providing a retrospective analysis classification; using at least one processor, creating, for each cardiac episode category, a subset of the plurality of cardiac episodes, each subset including greater than or equal to one episode and less than or equal to a predetermined number of episodes; and selecting, using the at least one processor, a respective subset of the plurality of cardiac episodes for display based at least in part on at least one of the IMD classification and the retrospective analysis classification.
