Ambulatory blood pressure monitoring (ABPM) measures blood pressure at regular intervals. It is believed to be able to reduce the white coat hypertension effect in which a patient's blood pressure is elevated during the examination process due to nervousness and anxiety caused by being in a clinical setting. Out-of-office measurements are highly recommended as an adjunct to office measurements by almost all hypertension organizations. 24-hour, non-invasive ambulatory blood pressure (BP) monitoring allows estimates of cardiac risk factors including excessive BP variability or patterns of circadian variability known to increase risks of cardiovascular event.
