Abstract

An implantable medical device (100) is provided for sensing cardiac events from electrodes (119, 121, 126, 127, 128, 129, 132, 134) located proximate to one or more atrial or ventricular sites, over a period of time that includes a detection period followed by an observation period. One or more processors (120) declare a ventricular arrhythmia episode and a corresponding VT/VF therapy based on the cardiac events during at least the detection period. The processors (120) delay delivery of the VT/VF therapy for a self-termination period within the observation period. The self-termination period represents a time period during which the ventricular arrhythmia episode may self-terminate. The processors (120) analyze a stability characteristic of interest (COI) from the cardiac events sensed over at least a portion the observation period and determine an end point for the self-termination period, within the observation period, based on the stability COI. The VT/VF therapy is delivered when the VT/VF arrhythmia episode continues past the end point.
