Diagnosis & Testing

Electrophysiology (EP) study - testing and mapping

An EP study records the electrical activity of your heart so that your heart specialist can find the cause of your heart’s rhythm disturbance and determine the best treatment. Multi-electrode catheters are inserted through your groin (rarely via your neck or collarbone area) and placed in the heart to determine the electrical patterns. As part of the EP study, physicians may:

  • reproduce an arrhythmia (irregular heartbeat)
  • give intravenous medications
  • map the arrhythmia in preparation for correcting the problem.

3-D Mapping: NavX and Carto™ mapping systems

These navigation systems use specialized 3-D mapping techniques used to locate the source of particularly complex heart rhythm problems. The 3-D mapping involves a catheter and a powerful computer. The computer processes signals picked up in the heart by the catheter then displays the information on a 3-D map of the heart chamber. This allows physicians to identify the exact source (or sources) of the irregular heartbeat.

Remote magnetic navigation

The Stereotaxis Navigation System uses magnets to guide catheters through the body. It is designed to improve many catheter-based cardiac procedures, including those used to treat both coronary artery disease and heart rhythm disorders. Swedish was one of the first places in the world to offer this advanced technology.

Diagnosing Atrial Fibrillation

In the video below, Dr. Darryl Wells of the Swedish Heart and Vascular Institute talks about how atrial fibrillation is diagnosed. There are some simple tests that can be done in the doctor's office that diagnose atrial fibrillation or rule it out.

Diagnosed with A Fib?

 
Atrial Fibrillation is no longer a condition you simply have to tolerate. Many treatments offer long-term solutions.
