Electrophysiology

Electrophysiology is the branch of cardiology that deals with problems related to the heart’s electrical system. The heart’s rhythm is regulated by a complex network of electricity beginning in the sinus node, a cluster of cells in the heart that serves as the heart’s natural pacemaker. Abnormalities in the heart’s electrical system are known as arrhythmias. In bradyarrhythmias, the heart beats too slowly, and in tachyarrhythmias, it beats too fast. Arrhythmias can be treated with a combination of lifestyle modification, medical therapy, and minimally invasive procedures. Learn more about electrophysiology procedures at MarinHealth.

A State-of-the-art Electrophysiology Laboratory

MarinHealth Medical Center was one of the first hospitals in the Bay Area to form a dedicated arrhythmia management program for complex ablation procedures. Our Electrophysiology (EP) Lab is one of the most advanced and integrated in the Bay Area. We are proud to provide world-class electrophysiology care to treat conditions spanning the entire spectrum of rhythm abnormalities.

We offer the latest services, technologies and procedures, including:

  • Cutting-edge cardiac implantable devices (like leadless pacemakers and defibrillators)
  • Arrhythmia mapping and navigation
  • Percutaneous hemodynamic support for life threatening arrhythmias such as ventricular tachycardia
  • Advanced catheter ablation procedures
  • Noninvasive monitoring of heart rhythm

Atrial Fibrillation Detection and Stroke Prevention

Atrial fibrillation, or “AFib”, is the most common serious cardiac arrhythmia, affecting an estimated 2.7 million Americans. According to the American Stroke Association, untreated AFib is responsible for roughly 15 percent of strokes. Unfortunately, the symptoms are not always noticeable; people may not realize there is anything wrong and dismiss minor symptoms as fatigue.

Our team is committed to reducing the risk of stroke in our patients using all available medications and technologies. AFib can be treated with blood thinner medications (anticoagulants). As an effective alternative to medication, we also offer percutaneous left atrial appendage occlusion. Our Electrophysiologists perform this procedure in collaboration with our Structural Heart team.

Catheter Ablation for AFib and Other Arrhythmias

Catheter ablation is a minimally invasive procedure that treats areas with abnormal electrical tissue through freezing (cryoablation) or cauterization (radiofrequency ablation). This treatment strategy can be effective or even curative for such disorders as supraventricular tachycardia (SVT), atrial fibrillation (AFib), and ventricular tachycardia (VT). We are able to offer the latest tools in electrical mapping and ablation to target these arrhythmias with exceptional outcomes in terms of safety and efficacy.

Implantable Cardiac Device (ICD) Insertion and Management

We are committed to providing cutting-edge device technology to ensure the best outcomes for our patients. We offer implantation and follow-up services for a full range of cardiac devices, including leadless ICD, leadless pacemaker, transvenous devices and cardiac resynchronization therapy (biventricular) devices. In 2018, we became the first Bay Area program to implant the Micra TPS, a completely leadless pacemaker that is introduced through a small incision in the groin and threaded up to the heart through the femoral vein. For patients with high-risk arrhythmias, our program recently began implanting the Impella® left ventricular assist device, a mechanical pump used to boost the heart’s pumping activity in heart failure patients. The Impella® device allows us to safely target even the most disabling rhythms in individuals with reduced heart function. Most recently, we have begun to offer patients with congestive heart failure the CardioMEMS device, a specialized pressure sensor to help keep them symptom-free and out of the hospital.

Get Into Rhythm: Living Well With Atrial Fibrillation (AFib)

Get Into Rhythm: Living Well With Atrial Fibrillation (AFib) is an innovative lifestyle management program led by our Medical Director of Electrophysiology, Sujoya Dey, MD, FACC. This comprehensive approach is designed to help patients with atrial fibrillation (AFib), the most common heart rhythm abnormality. Our Get Into Rhythm program offers education, counseling, and integrative healing modalities to help participants control their condition, avoid triggering an episode, and live healthier lives.

Physician referral is required to enroll in this program.
