What is ABPM?

Ambulatory blood pressure monitoring (ABPM) is a non-invasive method of obtaining blood pressure readings over a 24-hour period, whilst the patient is in their own environment, representing a true reflection of their blood pressure.

What does ambulatory blood pressure monitoring involve?

Blood pressure is measured over a 24-hour period, using auscultatory or oscillometry devices, and requires use of a cuff. The monitor takes blood pressures every 20 minutes (less frequently overnight – eg, one-hourly).

Who should get this test?

Your doctor might order an ABPM if you have these indications:

  • Suspected white-coat hypertension (including in pregnancy)
  • Suspected masked hypertension (untreated subject with normal clinic BP and elevated ABP)
  • Suspected nocturnal hypertension or no night time reduction in BP (dipping)
  • Hypertension despite appropriate treatment
  • Patients with a high risk of future cardiovascular events (even if clinic BP is normal)
  • Suspected episodic hypertension

Ambulatory BP monitoring may also be useful for:

  • titrating antihypertensive therapy
  • borderline hypertension
  • hypertension detected early in pregnancy
  • suspected or confirmed sleep apnoea
  • syncope or other symptoms suggesting orthostatic hypotension, where this cannot be demonstrated in the clinic
