What is ABPM?
Twenty-four-hour ambulatory blood pressure monitoring (ABPM) is a way of measuring and managing high blood pressure (hypertension). It allows your blood pressure (BP) readings to be recorded over a 24-hour period, whether you’re awake or asleep. In most cases, readings are taken every 20 to 30 minutes during the day and every hour at night. Your heart rate can be measured at the same time. These multiple readings are averaged over the 24-hour period. Changes in BP and heart rate, the BP distribution pattern and other statistics are calculated.
Indication of ABPM
- Used to confirm a diagnosis of hypertension.
- Used to detect White coat hypertension: elevated BP readings in a healthcare setting and normal at home.
- Used to detect Masked hypertension: elevated BP readings at home but normal readings in a healthcare setting.
- Used to detect Sustained hypertension: This refers to elevated BP readings in both health care settings or at home.
- Used to determine effectiveness of antihypertensive drugs.
- Used to diagnose People with “borderline” hypertension.
- Used to diagnoses Fainting episodes or hypotension (low BP).
Test Details
