SYSTEM AND METHOD FOR ASSESSING CLINICAL EVENT RISK BASED ON HEART RATE COMPLEXITY

摘要

The present disclosure generally relates to a system (100) and a method (200) for assessing risks of clinical events based on heart rate complexity of a subject (110). The system (100) comprises a physiological sensing device (120) and an electronic device (130). The method (200) comprises receiving (202), from the physiological sensing device (120), a physiological dataset measured from the subject (110), the physiological dataset comprising a set of heart rate data; generating (204) a heart rate time series from the heart rate data; calculating (206) a set of entropy data from the heart rate time series; calculating (208) an HRC index from the entropy data; comparing (210) the HRC index against predefined reference data; and (212) generating a risk signal in response to a determination from said comparing that the HRC index is indicative of increased risks of clinical events to the subject (110).
