Ambulatory Blood Pressure Monitoring (BP watch) is a test where your blood pressure and heart rate are taken at a fixed time interval for 24 hours, while you carry on with your daily activities.

It is particularly useful for patients with high blood pressure as it helps your doctor determine if your blood pressure medications are effective. It is also used to monitor borderline hypertension, young hypertension and poor blood pressure control. This 24-hour monitoring allows the doctor to study the variations of your blood pressure throughout the day.
