Holter

A Holter monitor is a battery-operated portable device that measures and records your heart’s activity (ECG) continuously for 24 to 48 hours or longer depending on the type of monitoring used. The device is the size of a small camera. It has wires with silver dollar-sized electrodes that attach to your skin. The Holter monitor and other devices that record your ECG as you go about your daily activities are called ambulatory electrocardiograms.

It may be used to see if you have a slow, fast or irregular (uneven) heartbeat. Or, to see how well your medicines/pacemaker is working to treat these problems.

This monitor has no risks and wearing it isn’t painful.

Regular electrocardiograms (ECGs or EKGs) look at your heart’s activity at one point in time during your ECG test. But abnormal heart rhythms and cardiac symptoms may come and go. That’s why to evaluate your heartbeat over time while you go about your normal activities.
