Abstract

A method of detecting atrial fibrillation (AFib) includes receiving electrical signals representative of a beating heart and measuring atrial activity over a time window of three or more beats. The method may also include measuring beat interval variation over the time window and combining the measures of atrial activity and beat interval variation to produce an indication of an atrial fibrillation condition in the electrical signal. The method may further include producing the indication with a processing system. Measuring atrial activity may include measuring P waves, and measuring P waves may include analyzing a standard deviation of a PR interval.
