Holter Monitoring

A Holter monitor is a small portable device that records heart rhythm. Holter monitor is used in monitoring various electrical activity of the central nervous system for at least 24 hours. The device records all of your heartbeats. A Holter monitor test is usually performed after a traditional test to check your heart rhythm

(electrocardiogram) isn't able to give your doctor enough information about your heart's condition.

The Holter monitor records electrical signals from the heart via a series of electrodes attached to the chest. These electrodes are connected to a small recording device that is attached to the patient's belt. The doctor uses information captured on the Holter monitor's recording device to figure out if you have a heart rhythm problem.

The recording device can be worn on a belt or in a case on a strap worn across the chest. Individuals who want to minimize the visibility of the device can wear layers or bulky clothes so the case is not as obvious. Also, because of the placement of the electrodes, individuals wearing a holter monitor may wish to wear shirts with a high neck.
