Abstract:
1. An apparatus comprising one or more machine-readable data storage media storing instructions operable to cause one or more data processing machines to perform operations, the operations comprising: receiving machine-readable heart rate information characterizing a heart rate of a monitored individual over a detection window; determining a quantity of bradycardia events present in at least a portion of the received heart rate information, wherein the determining comprises: deciding that a bradycardia event has occurred when at least one of the following is true: (i) the heart rate of the monitored individual is below a predetermined threshold and (ii) the heart rate of the monitored individual is below a baseline heart rate derived from at least a portion of the received heart rate information; detecting a cyclic variation in the received heart rate information; determining that obstructive sleep apnea is indicated over the detection window based on a combined analysis of the quantity of bradycardia events present in the received heart rate information and the detected cyclic variation in the received heart rate information; and selectively and individually reporting the obstructive sleep apnea event in real time in response to the determination that sleep apnea is indicated wherein the reported obstructive sleep apnea event is shorter than the detection window and overlaps at least in part with the detection window.
