When performing 24-hour ambulatory blood pressure monitoring, patients are allowed to walk and are advised to maintain a normal lifestyle so that the measured values are more reliable. However, when measuring blood pressure under pressure, it is recommended that you stop walking and straighten your arms to get a more accurate result. It is recommended to maintain a normal lifestyle and not to sit or lie down all the time, as this will make it difficult to assess whether the patient’s blood pressure rises higher during daily activities. Ambulatory blood pressure monitoring is to evaluate more objectively what the blood pressure is in a real life condition during a 24-hour day, and to further assess whether the patient has abnormal blood pressure.
