Holter Monitor and Event Loop Monitoring

A Holter monitor records the heart’s rhythm to help your heart doctor diagnose cardiac arrhythmia. The device is typically worn for 24 to 48 hours to record the heart’s rhythm when you have symptoms, like a continuous EKG (electrocardiogram).

An event monitor is similar to a Holter monitor except that it doesn’t continuously record your heart’s electrical activity. It only records during symptoms of arrhythmia. An event loop monitor, however, is always recording and erasing data. You activate it when you feel a symptom. A loop monitor may be external or implanted just under the skin on your chest.
