A Holter monitor recording is generally performed on an outpatient basis. Procedures may vary depending on your condition and your physician's practices.
Generally, a Holter monitor recording follows this process:
You will be asked to remove any jewelry or other objects that may interfere with the reading.
You will be asked to remove clothing from the waist up in order to attach the electrodes to your chest.
The technician will ensure your privacy by covering you with a sheet or gown and exposing only the necessary skin.
If your chest, arms, or legs are very hairy, the technician may shave small patches of hair, as needed, so that the electrodes will stick closely to the skin.
Electrodes will be attached to your chest, arms, and legs and the Holter monitor will be attached to the electrodes with lead wires. The monitor box may be worn over the shoulder like a shoulder bag, or it may clip to a belt or pocket.
Once you have been hooked up to the monitor and given instructions, you can return to your usual activities, such as work, household chores, and exercise, unless your physician instructs you differently. This will allow your physician to identify problems that may only occur with certain activities.
You will be instructed to keep a diary of your activities during the recording period. You should write down the date and time of your activities, particularly if any symptoms, such as dizziness, palpitations, chest pain, or other previously experienced symptoms, occur.
