Event Recording & Monitoring

An event recorder is a battery-powered portable device that you control to tape-record your heart’s electrical activity (ECG) when you have symptoms. There are two types of event recorders: a loop memory monitor and a symptom event monitor.

Cardiac event recorders and other devices that record your ECG as you go about your daily activities are also called ambulatory electrocardiographic monitors.

Quick facts:

  • A cardiac event recorder makes a record of your electrocardiogram (ECG or EKG) when you have fast or slow heartbeats, or feel dizzy or like you want to faint. It can also be used to see how you respond to medicines.
  • Some cardiac event recorders store your ECG in memory in the monitor. Your ECG can be sent by telephone to a receiving center or to your doctor.
  • There are no risks when using a cardiac event recorder.
