What We Do

An event recorder is similar to a holt​er monitor but it's worn for a longer period of time and used to record heart rhythm abnormalities that occur less frequently. You wear it during normal daily activities, including sleeping, but you'll also learn how to take the device off during showers and baths.

Small electrodes (sticky​ patches) are attached to your chest and connected with wires to the recorder. An event recorder saves a recording of your heart rhythm when it's activated. When you feel symptoms, you press a button to activate the recorder. The rhythm can be sent immediately or saved and transmitted later over the phone line.​
