Holter monitor is a small, battery-powered medical device that measures your heart’s activity, such as rate and rhythm .Twenty-four hour Holter monitoring is continuous recording of your heart’s rate and rhythm for 24 hours. You wear the Holter monitor for 12 to 48 hours as you go about your normal daily routine. It has electrodes and electrical leads exactly like a regular EKG, but it has fewer leads. It can pick up not only your heart’s rate and rhythm but also when you feel chest pains or exhibit symptoms of an irregular heartbeat, or arrhythmia. The Holter monitor lets your doctor see how your heart functions on a long-term basis.
If you’re already being treated for heart problems, wearing your monitor can help your doctor determine if your medicine is working or if changes need to be made.
