Therefore, it is best to measure blood pressure in both arms at home, with the side with high blood pressure as the criterion. In addition, in recent years, electronic sphygmomanometers are more and more used in families, and even in some large groups of people, electronic sphygmomanometers are also used in physical examination, but the real drug test and guidance of patients' medication are still based on desktop sphygmomanometers, which can reduce errors.
