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 (neck, torso). There is a lot more noise in the periphery, and these are already noisy metrics by their nature, prone to a lot of moment to moment and circumstantial variance. If pulse wave velocity is 6.3 m/s on day one and 8.5 m/s on day two, an entirely likely outcome, what exactly is one supposed to do with that information, other than resign oneself to a two to three week process of twice daily measurements in order to obtain a meaningful …
