1. A method of operating an implantable medical device, comprising:
- receiving a plurality of atrio-ventricular (AV) measurement signals;
determining a QT interval as a function of the AV measurement signals;
comparing each of the plurality of AV measurement signals with the QT interval; and
if one of the plurality of AV measurement signals is less than the QT interval, storing a difference between the one of the plurality of AV measurement signals and the QT interval.

Abstract
A method of operating an implantable medical device is provided. A plurality of atrio-ventricular (AV) measurement signals is received. A QT interval is determined. The QT interval is a function of the AV measurement signals. Each of the plurality of AV measurement signals is compared with the QT interval. Finally, if one of the plurality of AV measurement signals is less than the QT interval, a difference between the one of the plurality of AV measurement signals and the QT interval is stored.

11. An implantable medical device, comprising:
-
a processor;
a memory location operably connected to the processor; and
at least one sensing lead operably connected to the processor;
wherein a difference between one of a plurality of atrio-ventricular (AV) measurement signals sent by the at least one sensing lead and a QT interval is stored in the memory location for each of the plurality of AV measurement signals received by the processor that is shorter than the QT interval. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
