Electrophysiology Laboratory

Electrophysiology Laboratory in Grand Junction, CO

Cardiac electrophysiology (EP) is the study of the heart's electrical system. Practiced for about 20 years, EP studies involve insertion of a heart catheter to diagnose irregular heartbeat, for treatment, or to perform procedures such as pacemaker implantation procedure, defibrillator insertion, or ablation.

A relatively new EP procedure offers a permanent cure for atrial fibrillation, the most common type of arrhythmia, or irregular heartbeat, and a serious risk for stroke. Also, new hope for some heart failure patients is available with cardiac resynchronization therapy and implantation of a new type of pacemaker.

Procedures available at St. Mary's Electrophysiology Lab include:

  • Diagnostic Electrophysiology studies
  • Radiofrequency ablations
  • Pacemaker implants
  • Cardiac resynchronization therapy for chronic congestive heart failure
  • Implantable cardiac defibrillator device
  • Loop recorder implantation
  • Biventricular pacer/defibrillator implants
