Caring for patients having difficulty with the heart's rhythm and electrical signaling, our experts in Cardiac Electrophysiology and Pacing are the leaders in the diagnosis and care of patients with atrial fibrillation, ventricular tachycardia, Wolff Parkinson White syndrome, flutter and other abnormal heart rhythms. The Cardiac Electrophysiology and Pacing section has five state-of-the-art laboratories that offer a wide range of electrophysiology and mapping and ablation procedures to patients with suspected rhythm abnormalities. Other services include an Atrial Fibrillation Clinic, remote monitoring devices, genetic testing, a full range of pacemaker and cardioverter defibrillator (ICD) devices, biventricular pacemakers, removal of leads, advanced mapping and ablation therapy, Syncope Clinic and Device Clinic.

In the Cardiac Electrophysiology and Pacing section, we offer a variety of highly specialized approaches to heart-rhythm problems. The procedures may be used to diagnose a heart problem or to treat it. Arrhythmia treatment depends on the type and severity of the arrhythmia. In some cases of arrhythmia, no treatment is necessary. These include:

  • Center for Atrial Fibrillation, comprised of electrophysiologists, cardiologists, cardiac surgeons, imaging specialists and specially trained nurses and researchers, specializes in the diagnosis and treatment of atrial fibrillation using the newest medications, cardioversion, ablation (PVAI) and surgical procedures.
  • Sophisticated remote monitoring devices to help diagnose arrhythmias that come and go. New implantable devices are also available to help physicians monitor volume changes in the heart for those with heart failure and provide ongoing monitoring for those with complex arrhythmias or devices.
  • Physicians and nurses in our Device Clinic perform about 14,000 device checks each year to monitor the function of implanted devices.
  • Genetic testing to determine the presence of inherited arrhythmia disorders.
  • Medical management and follow-up of patients with arrhythmias, using the most current medical regimens available.
  • A full range of the newest pacemaker and cardioverter defibrillator (ICD) devices to provide individualized treatment for many irregular heart rhythms.
  • Biventricular pacemakers, to improve left ventricular function, in patients with heart failure. This treatment complements pacemaker and ICD therapy used to treat arrhythmias associated with heart failure.
  • Removal of leads from damaged and infected pacemakers or defibrillators.
  • Advanced mapping and ablation therapy in state-of-the art electrophysiology labs, for atrial and ventricular tachycardia.
  • Syncope Clinic uses a full range of diagnostic tests including the head upright tilt test and hemodynamic, blood volume and autonomic reflex testing to evaluate patients with syncope (fainting) or other neurogenic disorders.
What We Treat

What We Treat

Inherited arrhythmias are abnormal heart rhythms that are passed down from family members. They place you at risk for dangerous heart rhythms such as ventricular tachycardia and ventricular fibrillation and sudden cardiac death. The most common arrhythmias include:

Patients may have symptoms of fainting or a history of treated cardiac arrest – or – no symptoms but a family history of these conditions.

The experienced electrophysiologists and genetic experts in the Inherited Arrhythmia Center specialize in treating patients with these conditions.



EP Labs

EP Labs

The Electrophysiology Laboratory at Cleveland Clinic is an 8 room procedure suite designed to perform diagnostic, therapeutic and interventional electrophysiology based procedures.

Advanced technology along with vast knowledge and skill of Cardiac Electrophysiology and Pacing physicians allow for many complex procedures and device implants, such as:

  • Pacemakers
  • Internal cardiac defibrillators
  • Loop recorder devices
  • Biventricular pacemaker and ICD devices
  • Mapping of complex arrhythmias
  • Catheter ablation for atrial fibrillation/ flutter, supraventricular tachycardias, ventricular arrhythmias, complex arrhythmias and for those who have previously failed ablations.
  • Transseptal puncture and epicardial ablations
  • External or internal cardioversion
  • Device lead extraction
  • Use of intracardiac echocardiography
  • Magnetically driven procedures including ablations and coronary sinus lead placements

The Syncope Center, located near the electrophysiology laboratories performs approximately 2,000 diagnostic studies including tilt table testing, blood volume studies and other hemodynamic and/or autonomic nervous system evaluations.
