Ambulatory blood pressure monitoring
During this test your blood pressure is recorded over a 24 hr period. You wear a small monitor on a belt. This is attached to a cuff around your arm. During the day the cuff normally inflates every quarter of an hour allowing a recording to be made. During the night the cuff inflates less frequently. The recording shows how you blood pressure varies in every day life – as distinct from recordings made in the consultation room or surgery. We encourage you to be normally active whilst you are wearing the recorder. However you cannot use the shower, bath or go swimming whilst the recorder is attached. In a small percentage of cases the recording is unsuccessful for technical reasons and has to be repeated.
