A study by a Samsung Medical Center team led by Dr. Jin Wang Cho and Dr. Jong Hyun An found that blood pressure monitoring, available in the Galaxy Watch 3, Galaxy Watch Active 2 and the new Galaxy Watch 4, helps Parkinson’s patients track orthostatic hypotension. …
Orthostatic hypotension is common among people with Parkinson’s disease. Frequent measurement of blood pressure can reveal critical fluctuations. This is important, since with orthostatic hypotension in patients, possibly already suffering from cardiovascular diseases, the risks of a fall in this indicator increase.
The complex sensors in the company’s smartwatches monitor blood pressure by analyzing the pulse wave with heart rate monitoring sensors.Users can follow in the Samsung Health Monitor application and share them in PDF format. The research team found that “the use of wearable devices that are more portable and more convenient than a conventional sphygmomanometer allows Parkinson’s patients to measure their blood pressure anywhere, anytime.”
To do this, the researchers compared blood pressure measurements taken with the Galaxy Watch 3 with those of a sphygmomanometer. The test was performed three times on 56 patients with an average age of 66.9 years with a reference sphygmomanometer on one arm and a Galaxy Watch 3 on the other:
The test results showed that the pressure readings from the Galaxy Watch and the sphygmomanometer were comparable. The mean and standard deviation were 0.4 ± 4.6 mm Hg. Art. for systolic blood pressure (SBP) and 1.1 ± 4.5 mm Hg. Art. for diastolic blood pressure (DBP). The correlation coefficient (r) between devices was 0.967 for SBP and 0.916 for DBP. The closer the correlation coefficient is to 1, the higher the dependence of the results between the two devices.
