Detecting Sleep Disorders Using Heart Activity
First Claim
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 first interval;
detecting at least one of bradycardia and a cyclic variation in heart rate in the heart rate information during the first interval;
determining whether obstructive sleep apnea is indicated based at least on the detected at least one of bradycardia and cyclic variation in heart rate; and
selectively reporting an obstructive sleep apnea event in response to the determination that sleep apnea is indicated, wherein the obstructive sleep apnea event is a second interval when the information content of the received heart rate information is indicative of obstructive sleep apnea.

Abstract
Systems, methods, apparatus, and computer program products for detecting the existence of a sleep disorder in an individual using heart activity. In one aspect, machine-implemented methods include the actions of analyzing a machine-readable heart rate series of a monitored individual in the time domain using one or more digital data processing devices, detecting a cyclic variation in heart rate in the heart rate series as a result of the analysis in the time domain, and outputting, over an output, a report characterizing a sleep disorder event based on the detection of the cyclic variation in heart rate in the heart rate series. The cyclic variation in heart rate is indicative of a sleep disorder.
