Abstract
Aspects of the present disclosure are directed to detecting Atrial Fibrillation (AF). As may be implemented in accordance with one or more embodiments, a time series of inter-beat intervals is computed from a recording of activity of a beating heart. The time series is decomposed into subcomponents, and an envelope of at least one of the subcomponents is computed. The presence of atrial fibrillation (AF) is detected based upon characteristics of the envelope that are indicative of AF.
Claims1
A method comprising:
- computing a time series of inter-beat intervals from a recording of activity of a beating heart;
- decomposing the time series of inter-beat intervals into subcomponents;
- computing the energy of at least two of the subcomponents;
- and
- determining that atrial fibrillation is absent based upon relative energy of the at least two subcomponents.
