Electrophysiology Laboratory

Director: Mark E. Josephson, MD
Appointments: 617-667-8800

Most Advanced Diagnosis and Treatment Methods

The laboratory offers the most advanced diagnosis and treatment methods, including non-surgical procedures to control or cure a variety of arrhythmias including undiagnosed palpitations, syncope, superventricular and ventricular tachycardias, atrial flutter fibrillation, Wolff Parkinson White syndrome, risk of cardiac arrest, congenital or acquired basis arrhythmias and conduction disturbance not diagnosable by electrocardiograms (ECG) alone.

24-Hour Onsite Laboratory

The onsite laboratory provides 24-hour monitoring for arrhythmia diagnosis and management. Our experienced physicians achieve excellent outcomes with implantation of pacemakers, implantable cardioverter defibrillators (ICDs) and biventricular devices (a special kind of pacemaker). Pacemaker and ICD lead removal are also offered. Patients benefit from education and support groups.

Cardiac Electrophysiology Services

Cardiac electrophysiology services include:

  • Outpatient  arrhythmia management, in a clinic setting, for patients with even the most complex arrhythmias
  • Syncope (fainting) clinic with a special focus on treating unexplained syncope
  • Intensive electrophysiologic (EP) evaluation to diagnose both clinical  tachyarrhythmias (rapid heartbeats) and  bradyarrhythmias (slow heartbeats) and test the effectiveness of medications
  • Catheter ablation, a non-surgical procedure in which physicians deliver radiofrequency energy to abnormal areas of the heart to control or cure a variety of abnormal heartbeats
  • Defibrillator and permanent pacemaker implantation with follow-up in a pacemaker/device clinic that provides continuing education and support groups
  • Transvenous lead extraction, using the latest techniques, including laser sheaths, to remove scarred-over pacemaker and defibrillator wires from the heart
  • Biventricular pacing - a special kind of pacemaker that keeps the two lower heart chambers pumping blood in sync -- for patients with advanced heart failure
