Ambulatory blood pressure monitoring (ABPM) may become an indispensable tool in the diagnosis and treatment of hypertension if its precise role is determined. ABPM is accomplished with a special device that consists of a blood pressure cuff that is worn on your arm and is attached to a small recording device that you wear on your belt. You wear the ABPM device for either 24 or 48 hours, and it records your blood pressure periodically (usually at 15-minute or 30-minute intervals) throughout that period, during your routine daily activities and while you are sleeping. So, the ABPM provides your healthcare provider with a complete record of your blood pressure for a one or two day period.
