Estimation of Heart Rate from Photoplethysmographic Signal Using SVR Method

Abstract

Photoplethysmography is a non-invasive technique that measures relative blood volume changes in the blood vessels near to the skin. The early evaluation of the cardiac diseases and respiratory diseases can be done easily through PPG analysis. It has been used to measure indirectly heart rate, blood oxygen saturation (SPO2) and many other biological parameters. The proposed methodology is to detect heart rate from the noisy PPG signal using the singular value decomposition (SVD) method.
