Cardiac Electrophysiology

Electrophysiologists diagnose and treat abnormal heartbeats or arrhythmia.

Expertise and Innovation

For over 30 years our physicians have been nationally recognized experts in atrial fibrillation ablation, MRI imaging for arrhythmias, ventricular tachycardia ablation, implantable cardioverter-defibrillators (ICDs) including the subcutaneous ICD, prevention of sudden cardiac death, cardiac device infections including lead extraction, and arrhythmias in athletes. Through research protocols and FDA-approved therapies, we offer access to the newest technologies that frequently aren’t available elsewhere in the Northwest, like the Watchman device for atrial fibrillation.

Comprehensive Individualized Care

We offer care and support based on your needs. Your personalized treatment plan may include medication therapies, nonsurgical catheter procedures, minimally invasive surgery or advanced surgery when required.

Multidisciplinary Team Care

Our patients are treated compassionately in a collaborative setting, with a multidisciplinary team that includes experts in arrhythmia management and treatment, heart failure, cardiac transplant, cardiac surgery, cardiac anesthesia, infectious disease, cardiac imaging, structural heart disease, interventional cardiology, hypertrophic cardiomyopathy and congenital heart disease.

Common conditions and symptoms treated

  • Arrhythmias associated with congenital heart disease 
  • Arrhythmias during pregnancy 
  • Arrhythmias in athletes 
  • Atrial fibrillation and atrial flutter 
  • Hypertrophic cardiomyopathy (HCM) 
  • Inherited genetic disorders  
  • Patients needing cardiac implantable electronic devices 
  • Remote monitoring of pacemakers and implantable cardioverter-defibrillators (ICDs) 
  • Slow heart rates (Bradycardia) 
  • Sudden cardiac arrest (SCA) 
  • Supraventricular tachycardia including Wolff-Parkinson-White (WPW) syndrome 
  • Ventricular tachycardia and premature ventricular contractions (PVCs)
