The Electrophysiology (EP) & Arrhythmia service at the University of Wisconsin offers state-of-the-art diagnostic methods and advanced treatment options available for management of patients with cardiac arrhythmias.

Electrophysiology StaffThe EP team performs a full range of invasive procedures for treatment of cardiac arrhythmias.  In addition to the implant of cardiac pacemakers, implantable cardioverter-defibrillators (ICDs) and cardiac resynchronization therapy (CRT) devices, cardiac ablations are also performed for invasive management of conditions such as atrial fibrillation, atrial flutter, supraventricular tachycardia (SVT) and ventricular tachycardia (VT).

The UW EP & Arrhythmia service offers the latest advances in technology to treat arrhythmias, including:

  • Fluoroscopy-free ablation of supraventricular arrhythmias
  • Three-dimensional electro-anatomical mapping
  • Intracardiac echocardiography
  • Complex atrial ablation procedures
  • Epicardial mapping and ablation of ventricular tachyarrhythmias
  • Laser-assisted lead extraction of endovascular leads, with more than 100 leads extracted annually
  • Leadless cardiac pacemaker implants
  • Subcutaneous defibrillator (S-ICD system) implants
  • Left atrial appendage closure device implants

Other unique services offered to patients with suspected or established cardiac arrhythmias include:

  • Inherited Arrhythmias Clinic – specialized outpatient clinic that includes a dedicated genetics counselor, offering screening and assistance with diagnosis of rare genetic causes of arrhythmias and other cardiomyopathies
  • Faint and Fall Clinic – a truly multidisciplinary clinic that provides timely evaluation and management of patients with unexplained syncope (“fainting spells”) or falls, including real-time collaboration by different medical specialties such as Cardiology, Neurology and Geriatrics

The EP program provides a full-access outpatient clinic as well as an inpatient consultation service.  We perform over 600 ablation procedures per year, as well as over 800 device implants.  Outpatient care is provided at several clinic sites in Madison, such as UW Hospital, 1 South Park, Research Park and The American Center (TAC), in addition to outreach locations in South Central Wisconsin (including Beaver Dam, Darlington, Fort Atkinson, Mauston, Portage, Reedsburg, Richland Center and Sauk City). Our Device Clinics are responsible for the follow-up of more than 5,000 patients with cardiac implantable electronic devices.

The Heart Station performs nearly 32,000 ECGs, more than 2,200 exercise stress ECGs and 500 Holter and other ambulatory ECG recording studies annually. By offering the full range of inpatient and outpatient cardiac electrophysiology services, the EP program at UW seeks to provide the highest level of care in a patient-centered, evidence-based and cost-effective manner.
