The Electrophysiology Lab and MediGuide Technology

The Electrophysiology Lab located  within the Center for Advanced Heart Care utilizes MediGuide™ Technology. The University of Kansas Health System was the first in the nation to offer a new technology that provides a safer way for patients to have heart procedures. Called MediGuide, it incorporates GPS technology adapted for medical use to provide a real-time location of a heart catheter -- and show the path the catheter needs to follow to reach the problem area in the heart.

The benefit of using MediGuide is the dramatic reduction in radiation received by the patient and the hospital staff during procedures to treat atrial fibrillation and other heart rhythm irregularities. Used successfully in Israel and Europe, procedures at The University of Kansas Health System mark the first time this GPS-like technology has been used in the United States.

How does MediGuide work?

The technology uses electromagnetic signals to track miniature sensors embedded in MediGuide Enabled™ devices inside the heart showing the location throughout the procedure. The location is then superimposed on pre-recorded fluoroscopy images. It will be used in many heart procedures to treat atrial fibrillation and other rhythm abnormalities.

“Unlike the GPS in your car, which uses signals from a satellite to determine your location and your destination, The MediGuide™ Technology creates a GPS universe within the body. It shows the physician where the catheter is and the route to take to get to the damaged part of the heart. From there, the physician can ablate (eliminate) the problem heart tissue that causes the abnormal rhythm,” said Loren Berenbom, MD, director of the Richard and Annette Bloch Heart Rhythm Center at The University of Kansas Health System.

The real benefit of the procedure is the dramatic reduction in radiation received by the patient and the hospital staff during procedures. The current standard practice for viewing devices in the heart in real-time uses live fluoroscopy, which is a rapid series of X-ray images taken throughout the course of the procedure, which can take hours. With the ability to use pre-recorded images, instead of live X-ray during a procedure, MediGuide Technology reduces radiation exposure by 15- 90 percent.
