Abstract:
A method implemented with an implantable medical device, comprising:developing atrial and ventricular interval rates from sensed atrial and ventricular events, respectively; classifying atrial interval rates in an atrial window, the atrial window having a first length and a first satisfaction criterion; classifying ventricular interval rates in a ventricular window, the ventricular window having a second length and a second satisfaction criterion, the second length of the ventricular window differing from the first length of the atrial window to enhance detection of ventricular arrhythmias relative to atrial arrhythmia detection; declaring a ventricular episode in response to satisfying the ventricular window by comparing classified ventricular interval rates to the second satisfaction criterion; and declaring an atrial episode in response to satisfying the atrial window by comparing classified atrial interval rates to the first satisfaction criterion.
