The Cardiac Electrophysiology Service
The Cardiac Electrophysiology Service at Columbia University Medical Center has a long tradition of providing effective and comprehensive care for patients with abnormal heart rhythms. We offer a wide range of diagnostic and treatment services, including non-invasive risk stratification for arrhythmia, device implant, laser lead extraction, and catheter ablation for arrhythmias including atrial fibrillation and ventricular tachycardia.

Atrial Fibrillation- Columbia University has been high volume center for atrial fibrillation management and treatment since 2001. Dr. Hasan Garan and his team of electrophysiologists have extensive experience in catheter ablation procedures for treatment of atrial fibrillation. Other therapies, including novel drugs for atrial fibrillation, are also available at our center. We welcome any consultation requests.

Catheter Ablation - Columbia University Medical Center is a referral center for nonpharmacologic, curative catheter ablation procedures for all types of supraventricular and ventricular arrhythmias.

Biventricular Pacemakers-our physicians have a longstanding experience in device implantation, and Columbia has been involved in major studies of defibrillators and biventricular pacemakers since their first availability. Our staff physicians work closely with the physicians of CUMC Heart Failure department for the treatment of heart failure with biventricular pacing.

Lead extraction- Dr. Frederick Ehlert has specialized expertise in the removal of leads in individuals with damaged or infected devices.

Risk Detection for life threatening arrhythmias – we perform a range of diagnostic tests, including T wave alternans and cardiac electrophysiology studies, which may help estimate the likelihood of future arrhythmias, in patients thought to be prone to such rhythm disturbances.

Congenital Heart Disease – we work with Dr. Marlon Rosenbaum, Director of the Adult Congenital Heart Disease Center, to treat arrhythmias, in patients with congenital heart disease, using both device and catheter-based therapies.

Genetic Testing – we work with Dr. Wendy Chung of the Clinical Genetics division to evaluate individuals for the presence of inherited cardiac arrhythmia disorders or to screen the blood relatives of patients with known such disorders.
