Classification: CPC A  G | IPC A  G

Claim 0:
1. A method, comprising:
estimating, by a consumer electronic device, an atrial fibrillation (AF) burden of a subject based on multiple measurements passively collected by at least one sensor associated with the consumer electronic device while the subject is in a free-living environment;
outputting, by the consumer electronic device, an AF burden notification associated with the subject based on the estimated AF burden; and
outputting, by the consumer electronic device, an AF burden recommendation based on the estimated AF burden;
wherein estimating the AF burden comprises:
obtaining a first sequence of state values based on the multiple measurements collected by the at least one sensor, the first sequence of state values including past detected AF states and past detected normal sinus rhythm (NSR) states of the subject;
obtaining a transition probability matrix comprising values indicating probabilities of state transitions between an AF state and a NSR state;
obtaining an emission probability matrix comprising values indicating probabilities of one or more estimated AF states or one or more estimated NSR states arising from multiple observations; and
estimating a second sequence of state values based on the first sequence of state values, the transition probability matrix, and the emission probability matrix.
