Electrophysiology and Cardiac Arrhythmia Service

Yale New Haven Hospital heart rhythm specialists use the latest diagnostics, medications, devices and innovative approaches to care for patients with irregular heart rhythms, heart palpitations and slow and rapid heart rhythms.

Our cardiac electrophysiologists treat patients with all types of heart rhythm disorders, including:

  • Arrhythmogenic right ventricular cardiomyopathy
  • Atrial fibrillation 
  • Atrial flutter
  • Bradycardia
  • Brugada syndrome
  • Device follow-up, including remote home monitoring
  • Device infections
  • Long QT syndrome
  • Premature atrial and ventricular beats
  • Supraventricular tachycardia
  • Syncope
  • Ventricular arrhythmias
  • Ventricular tachycardia and fibrillation
  • Wolff-Parkinson-White

Available treatments:

  • Antiarrhythmic medications
  • Cardiac ablation, including catheter and complex procedures
  • Cardiac resynchronization therapy (CRT) for congestive heart failure
  • Complicated ablation procedures and pulmonary vein isolations
  • Diagnostic electrophysiology studies and risk stratifications
  • Electrical cardioversion
  • Implantable cardioverter defibrillators (ICDs) insertions (transvenous and subcutaneous)
  • Laser lead extractions
  • Left atrial appendage closure
  • Minimaze procedures
  • Implantable pacemaker insertions (transvenous and leadless)
  • Robotic remote navigation
  • Three-dimensional arrhythmia mapping and ablation

Yale New Haven's pediatric arrhythmia team provides electrophysiological diagnosis and treatment, including catheter ablations and pacemaker placement. There are also clinical trials related to electrophysiology and cardiac arrhythmias. To learn more, visit Yale New Haven Children’s Heart Center.

The Heart and Vascular Center and Children’s Heart Center provide the Family Inherited Arrhythmia Program in North Haven to identify and manage familial arrhythmia syndromes. It is the only combined pediatric and adult arrhythmia program in Connecticut offering consultation to children and parents, together, at the same appointment. Conditions or reasons for program evaluation include arrhythmogenic cardiomyopathy; Brugada syndrome; catecholaminergic polymorphic ventricular tachycardia (CPVT); idiopathic ventricular fibrillation; long QT syndrome; short QT syndrome; family history of sudden death. 

Maze Procedure Surgery

In some cases, surgical treatment is required to treat abnormal heart rhythms or arrhythmias. The maze procedure is a surgical treatment for atrial fibrillation. The surgeon can use small incisions in the heart tissue and burn or freeze the area, thereby creating scar tissue that does not conduct the electrical activity causing the atrial fibrillation. The scar tissue directs electric signals through a controlled path, or maze, to the lower heart chambers (ventricles) and can maintain a normal heart rhythm. Similar surgery can also be performed to treat ventricular arrhythmias. In addition, our surgeons can implant cardiac devices, including pacemakers, for abnormally slow heart rhythms and implantable cardioverter defibrillators (ICDs) for fast and life-threatening ventricular arrhythmias.
