Why do you need it?

By measuring blood pressure at regular intervals over 24 hours, your doctor is able to get a clear picture of how the blood pressure fluctuates throughout the day and night. There are a number of reasons why your doctor might suggest this test:

• To confirm if you do suffer from high blood pressure and how high are the readings over a 24 hr period.
• If your blood pressure readings are always high in the doctor’s clinic/ surgery, your doctor may want to know if blood pressure is actually lower outside the clinic – this is called the “white coat effect”.
• Your doctor may want to see how big are the fluctuations in your blood pressure throughout the 24 hr period.
• To see how well the medicines are working, and to make sure they are controlling your blood pressure throughout the day and night.
• To see if your blood pressure stays high at night. If this is the case, your doctor may want to change or adjust your medicines.

Procedure:

• You need to be booked for this test after consultation with a GP in our practice. Medicare in Australia rebate will available if you are eligible after a doctor’s assessment.
• The blood pressure cuff is wrapped and fixed around your upper arm – either arm can be used.
• The digital blood pressure machine itself is attached to a belt around your waist.
• Technician checks that battery life is sufficient for 24 hrs and checks if the machine operates well.
• The cuff inflates every 30-60 minutes as per the settings and then slowly deflates to record the blood pressure in its memory. This is no different from any other blood pressure machine.
• The blood pressure is recorded throughout the 24 hr period. Please do not switch it off at night as nighttime readings are equally important.
• Normally the machine is fitted by our experienced nursing staff.
• Because the test is being carried out to find out what your normal daily blood pressure is, it is important to carry on with your normal routine and do all the things you would normally do.
• The only things you should avoid doing for the day are swimming and having a bath or shower with the machine attached.
• At the completion of 24 hours you can either remove the machine and cuff yourself or come back to HeartWest where staff will take it off. If it’s worn on a Friday please make sure that it’s taken off and switched off after 24 hrs on Saturday and returned on Monday for the machine data to be analyzed.
• A formal report will then be completed by the reporting cardiologist and sent to your referring doctor whom you should see to get the results.
