For Referring Physicians


Dr. DAvilaOur electrophysiologists are internationally recognized in the management of all types of complex atrial and ventricular arrhythmia. We offer comprehensive services, which include state-of-the-art diagnostics, treatments, and minimally invasive procedures.

Leaders in Treating Ventricular Tachycardia

Program Director, Andre d’Avila, MD, is a leader in mapping and ablation of complex atrial and ventricular arrhythmias, including ventricular tachycardia. He and his colleagues in Brazil at the Hospital Cardiologico Florianopolis have pioneered the field of epicardial ablation and Dr. d’Avila was instrumental in bringing this technique to the United States.

A Range of Comprehensive Services

Diagnostics. Using state-of-the-art technologies, the arrhythmia monitoring lab staff work closely with our electrophysiologists to identify patients at high risk of sudden cardiac death and alert referring physicians when significant rhythm abnormalities are detected.

Atrial fibrillation management. Our Atrial Fibrillation Clinic includes consultation for afib ablation and anti-arrhythmic drugs, as well as cardioversion and access to clinical trials.

Device management. Both routine and urgent patient appointments are available daily in our Pacemaker and Defibrillator Clinic for:

  • Standard and novel leadless pacemakers
  • Implantable cardioverter defibrillators (ICDs)

Lead extractions. In consultation with BIDMC cardiac surgeons and infectious disease specialists, our electrophysiologists oversee one of New England's busiest practices in lead removal services.
