A holter monitor records your heart rhythm continuously throughout the day and night.
The length of time that you will need to wear the monitor will be determined by your cardiologist. The monitor can be worn anywhere from 12 hours - 7 days.
Should you be required to wear the monitor for longer than 24 hours you will be provided with a detailed instruction sheet as you will need to re-attach the monitor daily.
You will need to wear a loose fitting shirt or top as the technician will need access to the chest area. Bathe or shower on the morning of the test as you will not be able to do so for at least the next 24 hours. No other preparation is required.
The monitor is the size of a mobile phone and consists of 5 or 7 leads which are attached to your chest by adhesive electrodes with tape placed over the top to ensure they remain in place. It is important to check that the electrodes are in place throughout the day. Should you have an allergy to adhesive tapes please advise the technician fitting the monitor. The technician may also have to shave small sections of hair from your chest to ensure sufficient contact of the electrodes with the skin.
The holter will either be hung loosely around your neck by a strap or clipped onto your waistband. During the recording you will need to list your symptoms, the time they occur and what you were doing at the time on the diary sheet provided.
You will be able to carry out your normal daily activities BUT you must not get the monitor wet i.e. no swimming or showering, nor use an electric blanket or magnetic underlay.
You can disconnect the monitor yourself. The technician will demonstrate how to do so at the time the monitor is fitted. The monitor, grey leads and diary sheet will need to be placed in the envelope provided and returned at a specified time and place. It is important to return the monitor at this time as the data must be downloaded and the monitor prepared for the next patient.
Results will not be available at the time you return the monitor. The recorded data will be downloaded, reported by a cardiologist and the results forwarded to your referring doctor. Please allow 5 working days before making an appointment with your doctor or notify the technician if you have an appointment within the 5 days.
Full payment will be required on the day of the test.
If you are a patient undergoing this test and you have any further queries, please raise them with your cardiologist.
