Holter Monitoring

The Holter monitor is a type of electrocardiogram (EKG) used to monitor the EKG tracing continuously for a period of time.  It is a small, wearable device that keeps track of your heart rhythm. Small plastic patches (electrodes) are placed at certain locations on the chest wall. 

Your doctor may want you to wear a Holter monitor for one to two days. During that time, the device records all of your heartbeats.  The electrical activity of the heart can be recorded to evaluate for symptoms of lightheadedness, dizziness, palpitations, or fainting.  Any abnormal beats or rhythms that may cause these symptoms are recorded. ​

A Holter monitor test is usually performed after a traditional test to check your heart rhythm (electrocardiogram) if the electrocardiogram doesn’t give your doctor enough information about your heart’s condition.
