Abstract:
A method for accurate heart rate detection includes receiving a signal indicative of motion due to respiration, and using the signal indicative of motion to adjust a threshold value of a signal indicative of activity of the heart. The adjusted threshold value is used to detect an accurate heart rate of a patient. A system for accurate heart rate detection comprises a motion sensor which produces a signal indicative of motion due to respiration, and a processor which adjusts a threshold value of a signal indicative of activity of the heart according to the signal indicative of motion. The adjusted threshold value is used to detect an accurate heart rate of a patient. The motion sensor can be any device that can determine direction of motion, such as an accelerometer, a displacement sensor, a velocity sensor, or a photoplethysmography (PPG) sensor.
