About this study

Recently, wearables, like smartwatches, have been gaining new possibilities in monitoring biological signals and they are used for home monitoring of health conditions. Heart rate measurement is a common function of smartwatches, some smartwatch models even measure blood pressure. The study aims to compare the measurement of blood pressure and heart rate using the latest smartwatch with a vital signs monitor used in clinical practice. Blood pressure and heart rate measurements will be taken by hand from the watch and the vital signs monitor simultaneously. The agreement of the measurements of both devices will be evaluated.
