Long-term Accuracy and Stability of Blood Pressure Measurements From a Smartwatch: Prospective Validation Study

Experimental Validation of the Long-term Accuracy of Blood Pressure Measurement Using a Smartwatch

The aim of the study is to perform an experimental validation of the long-term accuracy of blood pressure measurement using the Samsung Galaxy Smartwatch

Blood pressure is one of the basic vital signs monitored and is one of the most important indicators of a patient's health status. Cardiovascular disease is one of the leading causes of death worldwide. One of the major risk factors for cardiovascular disease is hypertension, which is globally attributed to one third of deaths in the world population. To improve the prevention of hypertension, self-monitoring of blood pressure is increasingly recommended. This project involves an experimental validation of the long-term accuracy of blood pressure measurement using the Samsung Galaxy Smartwatch compared to a medical grade digital tonometer with a cuff placed on the arm.
