What is a Holter monitor?

ANSWER

If your heart seems to skip a beat, race, or work a bit too slow, you could have a condition called arrhythmia. A Holter monitor is a tool you use at home to track your heart's rhythm around the clock for a few days. Your doctor may call it "ambulatory electrocardiogram," or ECG. Ambulatory means walking or moving around. You can wear the Holter monitor or carry with you.
