1. A system for generating a display of post-processed sensing data associated with identification of a cardiac event, comprising:
- an implantable medical device for sensing cardiac signals and generating and storing sensing data, wherein the sensing data includes sensed cardiac events;
a processor configured to receive the sensing data, determine if one of an undersensing criterion and an oversensing criterion is met in response to the received sensing data, and detect an event as being one of an undersensed event and an oversensed event in response to a criterion being met;
an encoder configured to generate an episode display comprising event identifying codes in response to the sensing data received from the implantable medical device and to produce an adjusted episode display in response to an event being identified as being one of an undersensed event and an oversensed event; and
a display to display the adjusted episode display, wherein the encoder is further configured to compute an interval between sensed events from the sensing data and to recompute a time interval associated with an event that is identified as one of an undersensed and an oversensed event, and producing an adjusted episode display comprises displaying the recomputed interval, and wherein displaying the recomputed interval comprises formatting the displayed recomputed interval to indicate that the interval is a recomputed interval distinguishable from an originally computed interval between sensed events from the sensing data.

Abstract
A medical device system senses cardiac signals and generates and stores sensing data including sensed cardiac events. A processor receiving the sensing data is configured to detect undersensed and oversensed events. The processor generates an episode display comprising event identifying codes in response to the received sensing data and produces an adjusted episode display in response to an event being identified as an undersensed event or an oversensed event.
