Our goal is to be clear and understandable to
you regarding your care. We hope that you

your home. If you still have questions, concerns
or need any extra information, please feel free
to address your question to any of our staff in
the Diagnostic Department .
A Holter monitor is a continuous recording of
your electrocardiogram (ECG) for 24 hours. It
provides valuable information about the
function of your heart. The monitor is a small
machine which records the electrical impulses
that cause the heart to beat.
This recording enables the physician to see
what your heart does during normal daily
activity. It also helps the physician to know
how your heart responds to your medication.
When you arrive at our Diagnostic Department, a brief history of your condition will be taken. Your
chest will then be cleansed with an alcohol solution to ensure good attachment of the sticky ECG
electrodes. Any excessive hair will be shaved. This is to ensure a good application of the small
electrode pads to your chest.
Thin wires are then used to connect the electrodes to a small tape recorder. Once the electrodes and
wires are in place, the technician will run test strips. The recorder is secured to your belt or it
can be slung over the shoulder and neck with the use of a disposable pouch.
The recorder is worn for 24 hours and you are encouraged to continue with your daily activities. To
avoid getting the setup wet and damaging the recorder, you will not be able to shower for the
duration of the test. Also be sure that all pads and wires stay attached. Be careful not to crush
the cables and instrument while in use.
Press the event button at any time during the recording to register an event (what you do or feel at
that time). Event acknowledgement is given by led flickering continuously for approximately 7.5
A diary or log is provided so that you can record the event (for example: walking the dog, upset at
neighbor) and symptoms (for example: skipped heartbeats, chest discomfort, dizziness) together with
When writing in your dairy, use only the clock on the recorder for timing your entries. The Holter
monitor has an internal clock which stamp the time on the ECG strips. These can be used to correlate
the heart rhythm with symptoms or complaints. After 24 hours, the Holter monitor needs to be
returned to the laboratory. This can be removed by the staﬀ.
Multiple ECG strips are recorded on paper with a computer-generated summary that provides details
about your heart rate and rhythm during the recording. This information is then provided to your
Meals and medication may be taken as usual before the examination. Please bring with you a list of the medications you are taking. The only requirement is that you do not use talcum powder or lotion on your chest and wear loose-fitting clothes. Buttons down the front of a shirt or blouse is preferable. This makes it convenient to apply the ECG electrodes, and also comfortably carry the monitor in a relatively discreet manner.
It takes approximately 10 to 15 minutes to apply the monitor and less than 5 minutes to remove it. You will also receive directions. Allow 30 minutes before your appointment to register at the Outpatient Admitting Department. You will be directed to the Diagnostics Department.
Holter monitoring is extremely safe and no diﬀerent than carrying around a tape recorder for 24 hours. Some patient's are sensitive to the electrode adhesive, but no serious allergic reactions are known.
The report is provided to your physician, together with multiple ECG strips after the recording has been scanned by the technician.
If the technician sees a rhythm that is lifethreatening or potentially dangerous your physician is informed immediately.
Otherwise, it may take a few days before you get the official results from your physician's office. At that time, you may also receive additional recommendations based upon the results of the test. For example, a pacemaker may be recommended if you have blackouts and the Holter monitor shows a seriously slow heart beat during the test.
