What is a Holter Monitor?

A Holter monitor is a portable device that is used to continuously record the heart's electrical activity over a period of time, usually 24-48 hours. The device consists of a small recorder that is worn on a belt or carried in a pocket and a series of electrodes that are attached to the chest with adhesive patches.

The Holter monitor is used to diagnose and evaluate a variety of heart conditions, including arrhythmias (irregular heartbeats), coronary artery disease, and heart valve problems. It can also be used to monitor the effectiveness of treatment for these conditions.

During the test, the Holter monitor continuously records the heart's electrical activity and stores the data for later analysis. The device does not interfere with normal activities, and you can continue your usual routine while wearing the monitor.

At the end of the test period, the data from the Holter monitor is downloaded and analyzed by a healthcare provider or technician. The results of the test can help your healthcare provider determine the cause of any symptoms you are experiencing and determine the appropriate course of treatment.

It is important to follow any instructions provided by your healthcare provider and to inform them of any symptoms you experience while wearing the Holter monitor.
