Why would I need an event recorder?

An event recorder is used over an extended period of time to gather information about a heart rhythm problem (such as palpitations or skipped heartbeats) that comes and goes. Because the problem arises infrequently, it is possible that nothing abnormal will show up on a standard electrocardiogram (ECG) or even a Holter monitor test.

The event monitor gives you and your doctor more time to get to the bottom of your heart problem. While a standard ECG records the electrical activity of your heart for only a few seconds, and a Holter monitor for 24 to 48 hours, an event recorder is typically worn for 30 days or more.

An event recorder is often used to determine whether certain symptoms are the result of an abnormality in the heart's rhythm. Common reasons for using an event recorder are:
  • Unexplained fainting or dizziness
  • Palpitations, or the feeling that your heart is fluttering or beating too hard or too fast
  • A suspected shortfall in the amount of oxygen-rich blood reaching the heart, or ischemia
  • Evaluation for an implantable cardioverter-defibrillator to treat a rapid heart rate
If you have already been diagnosed with a heart problem, your doctor may also use an event recorder to gauge how well your therapy is working.
