Abstract:
1. A method for detecting and classifying an arrhythmia, comprising: sensing a cardiac electrogram signal; determining a cardiac rate in response to the sensed cardiac electrogram signal; detecting an arrhythmia in response to the cardiac rate; sensing an intracardiac pressure signal; generating a parameter corresponding to a frequency content of the pressure signal; comparing the parameter to predetermined criteria; and classifying the arrhythmia in response to the comparing, wherein the arrhythmia is classified as a first arrhythmia in response to the parameter meeting the predetermined criteria and as a second arrhythmia in response to the parameter not meeting the predetermined criteria, wherein the sensed cardiac electrogram signal corresponds to an atrial signal, the determined cardiac rate corresponds to an atrial rate, and the sensed pressure signal corresponds to an atrial pressure signal, and wherein the first arrhythmia corresponds to atrial flutter and the second arrhythmia corresponds to atrial fibrillation.
