Holter Monitor

What is a Holter Monitor? Also known as an ambulatory ECG or EKG monitor, a Holter monitor records your heart’s activity over 24 to 48 hours while you maintain a diary of your activity to help your doctor identify the cause of your symptoms. Electrodes attached to your chest record information on a portable, battery-operated monitor that you can carry in your pocket, on your belt, or on a shoulder strap. What is a Event recorder? Symptoms that don’t happen very often may require an event recorder. It’s similar to a Holter monitor, but it records your heart’s electrical activity just when symptoms occur. Some event recorders activate automatically when they detect symptoms. Other event recorders require you to push a button when you feel symptoms.
