Heart Rate Variability of Photoplethysmography for Hypertension Detection Using Support Vector Machine

by

Abstract: Early detection of hypertension is essential as it is a common chronic age-related disease often associated with debilitating cardiovascular complications. The aim of this article is to find the best accuracy performance in detecting hypertension. This article introduced a method for hypertension detection without a cuff using parameters of photoplethysmography (PPG) and support vector … Read more

Photoplethysmogram peaks detection based on moving window integration and threshold for heart rate calculation on android smartphone

by

Abstract: We present a photoplethysmogram peaks detection and heart rate calculation on android smartphone. Photoplethysmogram signal is obtained and extracted from a video stream of fingertip that is taken from smartphone camera. Then, photoplethysmogram peak is detected based on moving window integration and threshold. The heart rate value is calculated from the detected peak. We … Read more
