Ambulatory Blood Pressure Monitoring Up to 65% of people who have high blood pressure readings in the office ARE NOT diagnosed as having high blood pressure after ambulatory blood pressure monitoring. Data suggests that in-office blood pressure checks may not be enough to diagnose high blood pressure. An ambulatory blood pressure monitor is a special blood pressure cuff that is worn on your arm and is attached to a small recording device that you wear on your belt. You will wear the monitor for 24 hours and it records your blood pressure every 15 to 30 minutes while you go about your day and while you are sleeping.
