For a more accurate diagnosis


The Holter test is a continuous, non-invasive recording of the electrocardiogram for 24 hours or more. It is usually used to diagnose arrhythmias that can not be distinguished during a resting or stress ECG.

During one whole day you will wear a Holter monitor (a small device that continuously records the ECG) which is connected to small electrodes placed on your chest and allows recording of the pulse and the heart rhythm during 24 hours. The monitor installation takes a few minutes and you wear it in your pocket or in a small bag around your neck or on your belt. You are free to conduct your usual daily activities (except taking a shower or a bath). During the day, you should write down on a log all your activities, any pain, discomfort or palpitation experienced, the drugs taken as well as and the time and duration of each event. At the end of the testing, the device must be returned to the clinic. The recording, made on tape, is digitized by the computer in order to be decoded and analyzed by the cardiologist.

If you believe you suffer from a heart rhythm problem, feel free to ask one of our doctors to prescribe you a Holter test. If you have a prescription for a Holter test, you can call 514 747-8185 to book an appointment. We will quickly forward your results to your physician.
