Brief summary

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

Detailed description

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.

Interventions

OTHERLong-term non-invasive Blood pressure monitoring

All measurements during the experiment include only non-invasive Blood pressure and Heart rate measurements. Measurements will be taken using a smartwatch attached to the wrist and a digital tonometer with a cuff placed on the other arm. Paired readings will be compared.
