    摘要： A system and method for Heart Rate Variability (HRV) data collection and analysis is presented to provide more specific guidance that is based on user HRV data, such as customized scores, customized modifications to specific plans or programs, e.g., guided breathing programs, athletic training plans, validations of treatments or events expected to have an impact on HRV readings. The collected HRV data may be used in live biofeedback type applications, such as including HRV scores or composite scores using HRV data as display graphics in streaming services, using HRV scores or composite scores to modify the behavior of systems such as gaming systems, vehicles, content recommendation systems, ad selection systems, etc. The system and method also presents a user display for teams or groups, with HRV related statistics and recommendations available at various levels of granularity (e.g., group or team, sub-group, individual).

    摘要： The proposed technology relates to a method for indicating a risk for coronary artery disease. A sound recording is obtained (100) covering a plurality of heartbeats, a plurality of heart sounds are identified (200) in the sound recording, and a plurality of segments are obtained (300) from the sound recording. A frequency power measure is determined (400) based on the signal strength of a first frequency window of a period in the diastole, an amplitude of the fourth heart sound is determined (500) based on the plurality of heart sounds and the plurality of segments, and an indication of a heart rate variability is determined (600) based on the plurality of heart sounds. The indication of the risk for coronary artery disease is then determined (700) based on the frequency power measure, the amplitude of the fourth heart sound, and the indication of the heart rate variability.
