1. A method for determining a metric of the occurrence of non-sustained arrhythmias comprising;
- detecting non-sustained arrhythmia episodes as episodes;
storing characteristic data related to the non-sustained arrhythmia; and
calculating a metric of non-sustained arrhythmias based on the stored data; and
adjusting a parameter for detecting a sustained arrhythmia based on the metric of non-sustained arrhythmia occurrence, wherein stored characteristic data includes one of a number of non-sustained arrhythmia episodes within a specified period of time, a duration of a non-sustained arrhythmia episode, a cycle length during a non-sustained arrhythmia episode, and a cardiac signal morphology during a non-sustained arrhythmia episode.

Abstract
An implantable medical device and associated method are provided for detecting non-sustained arrhythmias and determining a metric of non-sustained arrhythmias. The metric may be used for predicting the occurrence of a sustained arrhythmia or for automatically adjusting the parameters used for detecting a sustained arrhythmia.
