SYSTEM AND METHOD FOR EVALUATING A VARIATION OF A HEART RATE OF A SUBJECT

机译:评估对象心率变化的系统和方法

摘要

The present invention relates to a detection of physiological signals of cardiovascular systems. In particular, it relates to a system and method for more reliably evaluating a variation of a heart rate of a subject. The system comprises a photoplethysmography (PPG) signal providing unit (10); a motion signal providing unit (20); a motion determination unit (40) for determining a motion period during which motion identifiable in the motion signal corresponds to one of a plurality of predefined motion classes; a signal reliability determination unit (50) for determining a signal reliability of the PPG signal depending on a motion influence period, wherein the motion influence period comprises the motion period and a transition period following the motion period; and a heart rate variation determination unit (60) for determining the variation of the heart rate of the subject based on the signal reliability and on the PPG signal.
