Ambulatory Blood Pressure Monitoring


Ambulatory Blood Pressure Monitoring is a non-invasive investigation in which your blood pressure is recorded over 24 hours. This method of monitoring provides our specialist cardiologist’s important information about how your blood pressure changes over the course of the day. This then allows individualised treatment for your condition.

When the heart beats, blood is pumped through the arteries pushing against the vessel walls which are muscular and flexible. The amount the blood pushes against the artery walls is measured in units of pressure and is known as your blood pressure. The more forcefully blood pumps around the body the higher blood pressure.

  • To diagnose high blood pressure.
  • Some people have high blood pressure when measured by healthcare professionals. This is called ‘white coat hypertension’. Therefore, this test can be used to rule out high blood pressure these otherwise healthy people.
  • If you are on blood pressure treatment then we can assess how well your blood pressure medications are working.
  • To assess exactly at what times in the day your blood pressure increases or decreases.
