About Your Holter Monitor

Also called: Continuous EKG, Continuous Ambulatory EKG

What Is a Holter Monitor ?

The heart uses electrical impulses to tell the chambers when to contract to pump blood throughout your body, by measuring these impulses, your doctor can determine if your heart is functioning properly. Sometimes, an in office electrocardiogram (EKG) might be taken, but this only gives a brief snapshot of your heart's health. For a clearer picture of how your heart's rhythm changes throughout the day, your doctor could ask for continuous monitoring for a day or two using a Holter monitor. These record your heart patterns throughout your daily activities. Holter monitors are portable EKGs, and like EKGs are painless. The results given from one will be a more accurate reflection of your average heart rhythm than a single reading taken in your doctor's office.

How Is the Test Performed?

Sensors will be taped to your chest, and a portable recording device will be given to you. Be careful to not let the sensors fall off. Bathing and activities which might pull at the sensors or wires should be avoided, but keep to your regular schedule as much as possible. You should keep a diary of your daily activities and physical symptoms, including any medications you take and when for the entire time the Holter monitor is attached. This could last between 1 and 5 days.

After the Procedure

The sensors will be removed and the results from the Holter monitor will be evaluated. Your doctor will then decide on further tests, medications, or recommendations after that.          

Is It Safe?

Holter monitors do not send electrical impulses to the heart. Instead, they simply monitor those that the heart sends. A Holter monitor is a non-invasive, painless test with no side effects.
