Holter Monitoring

What is a Holter Monitoring test?

A holter monitor is a small, portable tape recorder that records your EKG (your heart's electrical activity) for twenty-four hours. Holter monitoring provides your physician with continuous EKG recording during your daily activities. It is helpful in diagnosing abnormal heart rhythms.

Indications:

Your physician may order a holter monitor to:

# Detect abnormalities that may not occur during a regular EKG
# Evaluate symptoms such as dizziness, syncope, and palpitations
# Assess the effectiveness of treatments, such as medications and pacemakers

What can I expect during the procedure?

Electrodes will be placed on your chest after it has been cleaned to remove oils and shaved, if required. Lead wires from the recorder will be attached to the electrodes. A new cassette tape and battery are placed in the recorder and a test EKG is recorded. The recorder is then placed in a holding pouch with a strap so you are able to carry it with you during throughout the 24-hour period. You will be given a diary to list any symptoms that you notice during the test. The recorder is also equipped with an event marker to be pressed when symptoms occur. You will return in 24 hours to have the monitor removed. The tape will be put into a special computer to scan your EKG.

A cardiologist will read the test and dictate a report for your doctor. The information received from holter monitoring helps your physician make an accurate diagnosis and plan a treatment best suited for you.

How do I prepare for the test?

There is no special preparation required.
