Frequently Asked Questions
What Does a Holter test do?
A Holter monitor is a small, wearable device that keeps track of your heart rhythm. Your doctor may want you to wear a Holter monitor for one to two days. During that time, the device records all of your heartbeats.
Why should I do a Holter test?
Your doctor may prescribe a Holter test if you have signs or symptoms of a heart problem, such as an irregular heartbeat (arrhythmia) or unexplained fainting. A Holter monitor test gives your doctor a beat-by-beat record of your heart’s rhythm for a long period of time.
What clothes should I wear before the appointment?
Wear loose fitting shirt or blouse with buttons in the front.
Can I exercise with the monitor on?
You can do anything you would normally do, except take a bath or shower while the monitor is on. Do not get the electrodes, wires, or recorder wet.
Can I take a bath/shower whilst undergoing monitoring?
No. The Holter monitor cannot get wet or be removed during a bath. Preferably bathe before the appointment.
Do I need to keep a dairy of the records during the monitoring?
Keep a diary of all the activities you do while wearing the monitor. It is particularly important to record in the diary any symptoms of palpitations, uneven heartbeats, shortness of breath, chest pain or light-headedness. This will help the doctor correlate your symptoms with your ECG tracing.
What care should I take while undergoing Holter monitoring?
⚫ Keep your portable electronic devices (cell phone, PDA, mp3 player) at least 6 inches away from the monitor; they can interfere with the monitor’s signal. ⚫ Do not go near high voltage electrical equipment, microwaves, magnets, metal detectors or electric razors, electrical toothbrushes, or blankets while wearing the monitor as these may interfere with the transmission of the signal between the sensors and the monitor. ⚫ Try to sleep on your back, with the recorder positioned at your side so that the electrodes are not pulled off. ⚫ Please do not tamper with the recorder, electrodes, batteries, or wires. If you do, the test may need to be repeated, resulting in additional expense for you. If one of the electrodes becomes loose, call the testing center immediately.
Are there any risks of Holter test?
There are no significant risks involved in wearing a Holter monitor other than possible discomfort or skin irritation where the electrodes were placed.
What does my Holter test report tell me?
The information from the Holter monitor may reveal that you have a heart condition, or your doctor may need more tests to find out what may be causing your symptoms. Your doctor will compare the data from the recorder and the activities and symptoms you wrote down. This will help him make further treatment plans.
