PADUA, Italy – The reliability of blood pressure measurement with wrist devices is dependent upon the correct positioning of the wrist device at heart level, a new study from the University of Padua suggests. The study included 721 participants who were trained to use upper-arm and wrist devices. Their blood pressure was measured in a doctor’s office with both devices, then self-measured at home for seven days. Using the office measurements as the reference, the study found that a total of 620 patients had inaccurate measurements at home, with more than 10 having discrepancies of more than 10mm/Hg. The study found that the use of wrist devices for home self-measurement leads to frequent detection of falsely elevated blood pressure values because the device is in the wrong position on the wrist.
