What is a Ambulatory
Blood Pressure Monitoring?
Office-based blood pressure measurements are notoriously inaccurate for many reasons, including the “white coat” effect and do not adequately reflect diurnal and activity-related variations. 24-hour ambulatory blood pressure monitoring (ABP) is recognized as one of the most effective and reliable ways to measure the blood pressure in clinical practice.
A small electronic device the size of a portable radio worn on a belt around the waist is attached to a blood pressure cuff which is inflated at 15-minute intervals during the day and 30-minute intervals at night. The approximately 80 individual pressure and rate data points displayed in numerical and graphical formats along with diurnal max/min/average information form the basis of important decisions, including the need for and the adequacy of antihypertensive therapy in a variety of clinical contexts.
