Pulse Sharpness Correlates with Vascular Aging

Consumer devices that can measure useful age related cardiovascular metrics such as pulse wave velocity and heart rate variability are not that great in comparison to the much more expensive lines of medical devices. The most important difference lies in whether measuring these parameters in the periphery (arm, wrist, finger) or in the body itself...
