Abstract:
An apparatus includes a sensing circuit configured to generate a sensed physiological signal representative of cardiac activity of a subject, and an arrhythmia detection circuit. The arrhythmia detection circuit is configured to monitor information corresponding to ventricular depolarization (V-V) intervals using the sensed physiological signal; determine a V-V interval distribution; determine a heart rate density index (HRDI) as a portion of samples of the V-V interval distribution corresponding to a V-V interval occurring most often in the distribution; and generate an indication of atrial fibrillation (AF) using the HRDI.

Claim (Index 8):
The apparatus of  claim 7 , wherein the measure of V-V interval dispersion includes a variance of the determined interval differences; and wherein the arrhythmia detection circuit is configured to determine the indication of AF when both of i) the determined variance satisfies a specified variance threshold value and ii) the determined heart rate mode satisfies the specified heart rate mode threshold value or the determined HRDI satisfies the specified HRDI threshold value.
