What is
Holter Monitoring?

Holter Monitoring is a continuous recording of the ECG using a cellphone-sized device connected to the chest using 5 electrodes for periods of 24, 48 or 72 hours or 7 or 14 days. The test provides essential information about the heart’s rhythm and is used to investigate symptoms such as palpitations, skipped beats, lightheadedness and fainting and to detect arrhythmias associated with certain cardiac conditions which can result in syncope, stroke or sudden cardiac death.

​

What to Expect

—

The skin is cleaned and the electrodes are attached firmly to the chest. The device is worn under clothes, either on a belt or around the neck. You will be asked to record symptoms and activities in a diary and to depress the event marker on the device in case of symptoms. For longer-term recordings you will be provided with additional electrodes to allow you to remove the recorder to take a shower.

How to Prepare

—

No special preparation is required.
