24 hour Holter Monitor

Holter monitors are sometimes called continuous ECGs (electrocardiograms). This is because Holter monitors record your heart rhythm continuously for 24 to 48 hours. A Holter monitor is about the size of a large deck of cards. You can clip it to a belt or carry it in a pocket. Wires connect the device to sensors (called electrodes) that are stuck to your chest using sticky patches. These sensors detect your heart’s electrical signals, and the monitor records your heart’s rhythm.
