Electrophysiology

If you have a heart rhythm disorder, you need a team with expertise to get your heart beating as it should. Our Electrophysiology Program offers specialized diagnosis and up-to-date treatments for common and complex arrhythmias. Our skilled team coordinates your care, so you can focus on recovery and getting back to the activities you enjoy.

Conditions we treat

At Dignity Health, our electrophysiologists treat all types of conditions affecting the heart’s electrical system. We have experience in arrhythmias caused by underlying heart conditions such as coronary artery disease, valvular heart disease, adult congenital heart disease and cardiomyopathy. 

Our team has specific expertise in various types of arrhythmias, some of which can become life-threatening. The conditions we treat include:

  • Atrial Fibrillation
  • Bradycardia (slow heart rate)
  • Genetic heart disorders 
  • Sudden cardiac arrest
  • Tachycardia (fast heart rate)

Procedures Performed in the Electrophysiology Lab:

  • Cardioversions
  • Cryoballoon ablation
  • Diagnostic EP Study
  • Implants of:
    • Bi-ventricular ICD
    • Bi-ventricular pacemaker
    • Implantable cardioverter defibrillator
    • Loop recorder
    • Permanent pacemaker
  • Laser Lead Extraction
  • Leadless pacemaker placement
  • Noninvasive programmed stimulation (NIPS)
  • Radiofrequency ablations (with and without 3-D mapping) of:
