Holter Monitor Q & A

What is a Holter monitor?

A Holter monitor is a portable device used to continuously record the heart’s electrical activity over a 24 to 48-hour period (sometimes longer). It helps diagnose irregular heart rhythms and other cardiac issues that may not be detected during a standard EKG.

Why would I need a Holter monitor?

A Holter monitor is typically used if you experience symptoms like palpitations, dizziness, or chest pain that are not captured during a routine EKG. It helps your doctor assess how your heart functions over an extended period and identify any abnormal rhythms or issues.

How is a Holter monitor used?

The monitor consists of a small device attached to your chest with electrodes. You’ll wear the device on a strap or in a pouch, and it will continuously record your heart’s activity as you go about your daily activities. The device is usually worn for 24 to 48 hours.

What should I do while wearing the Holter monitor?

You should go about your normal daily activities while wearing the Holter monitor, but avoid activities that might dislodge the electrodes, such as swimming or heavy exercise. Keep a diary of your activities and any symptoms you experience during the monitoring period, as this information can help your doctor interpret the results.
