Twenty-four-hour ambulatory blood pressure monitoring, also known as 24-hour ABPM, allows continuous monitoring and measuring of blood pressure, which allows subsequent management of high blood pressure (hypertension), if diagnosed. It is worn while you undergo your usual daily activities, including sleep. Most commonly, the readings are taken every 30 to 60 minutes during the day and every hour at night. These multiple readings are then averaged over the 24-hour period. 24-Hour ABPM ensures the cardiologist is aware of any changes in BP and heart rate, the BP distribution pattern and other relevant statistics.
This test provides a more accurate assessment of your blood pressure than office readings. For example, this monitor may be used to exclude hypertension (high blood pressure) in individuals who have elevated blood pressure readings when they visit their doctor due to anxiety (i.e. “white coat” hypertension).
Ambulatory BP monitoring is important as it can detect abnormal changes in BP that might go unnoticed when checked only in the doctor’s office. Dr. Nasis may use ambulatory BP monitoring to provide additional information about how changes in blood pressure correlate with a patient’s daily activities and sleep patterns. The cuff can be removed by yourself after being worn for 24 hours, following which it is returned for analysis by Dr Nasis.
