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
