Feasibility and Effectiveness of a Ring-type Blood Pressure Measurement Device

The goal of this clinical trial is to evaluate the feasibility and effectiveness of a ring-type blood pressure measurement device compared to a 24-hour ambulatory blood pressure monitoring device in patients with hypertension or suspected hypertension. The main question it aims to answer is whether the 24-hour blood pressure measurement accuracy of the ring-type blood pressure monitor is similar to that of the 24-hour ambulatory blood pressure monitor. To participate, subjects must wear a ring blood pressure monitor and an ambulatory blood pressure monitor simultaneously for 24 hours.
