Atrial Fibrillation Express Test

The Atrial Fibrillation Express Test (AF Express) is used to detect atrial fibrillation, an abnormal heart rhythm. This small device records the heart's electrical activity (rhythm) at the push of a button. Patients trigger the device when they first begin to feel the following signs:

  • Dizziness
  • Weakness
  • Lightheadedness
  • Heart racing and/or fluttering

The monitor stores the heart rhythm. Later, that rhythm is sent via the telephone to the doctor for review. This test allows for on-demand heart monitoring outside the hospital/clinic setting when symptoms are noted and as you go about your normal routine.

The AF Express also detects and records atrial fibrillation when the patient does not have any outward signs. The test results help guide your doctor to choose treatment options to meet your specific needs.

The monitor, about the size of a deck of cards, is clipped to your waistband. This monitor is connected to a set of wires which attaches to two electrodes worn on your chest (like an EKG). The monitor can be worn for up to 30 days (it is removed during bathing).

If you have any questions about the monitor use or care, please call the Bluhm Cardiovascular Institute Cardiology Clinic at 312-695-4965.
