Heart rate variability detector based on embedded system

Abstract

A kind of heart rate variability detector based on embedded system is researched, which gets the heart rate parameters with the photoelectric volume pulse and works out heart rate variability conveniently and noninvasively in real-time. The detector obtains volume pulse wave through the sensor of photoelectric volume pulse wave and sends it to the Amplification circuit, filter circuit, and A/D conversion and then into real-time microprocessor. In the microprocessor, signal is processed and parameters are obtained.
