A Holter monitor test is a non-invasive exam (i.e., it does not require opening the patient) that continuously records all of a person's heartbeats over a period of 24 to 48 hours. The heartbeats are recorded on a memory card that is then analyzed by a cardiologist.

Preparation
During a visit to the ambulatory clinic, self-adhesive electrodes are attached to the patient's chest and then connected to a recording device. The patient can wear this device attached to a strap or on a belt.
For this visit:
- Bring a full and updated list of medications
- Avoid applying body lotion before the exam
- Wear loose clothing and a shirt with a high collar (so that the device is not noticeable)
At the appointment, a technologist will install the device and give instructions for the next 24 or 48 hours. Patients then carry on with their normal routine while wearing the device, which they must bring back at the time indicated by the technologist.
The device must not get wet (in the pool, bath or shower), and patients must continue with their normal daily activities (note that sports must be avoided).
A cardiologist analyzes the content of the memory card and sends the results to the requesting physician.
