24 Hour Ambulatory Blood Pressure Recording

What is an ambulatory blood pressure monitor?

It is a device that enables multiple blood pressure recordings over a 24 hour period.

How is an ambulatory blood pressure monitor performed?

A technician or practice assistant will place a standard blood pressure cuff around your upper arm. This is connected to a small pump and recorder (similar in size to a large mobile phone). The cuff automatically inflates at regular intervals (every 30-60 minutes). The blood pressure cuff may cause minor discomfort on rare occasions. You may simply take off the cuff if this becomes intolerable for you.

Why is an ambulatory blood pressure monitor performed?

To monitor blood pressure changes throughout a 24 hour period and to obtain average day time and night time blood pressure readings. This test provides a more accurate picture of your blood pressure levels when compared to one-off readings when visiting doctors. It is also used to rule out hypertension in patients who have high blood pressure readings only when they visit a doctor, termed “white coat hypertension”, and to assess response to antihypertensive medications.

Do I need to prepare for an ambulatory blood pressure monitor?

Yes. You cannot take a bath or shower with a monitor on, since it is not waterproof. Please inform your cardiologist should there be any change in your blood pressure medications when you were wearing the monitor. You should continue usual daily activities while wearing the monitor. It is often useful to obtain blood night time blood pressure readings so try to keep the monitor on while sleeping
