Arrhythmia and Electrophysiology

Arrhythmia is an irregular or improper beating of the heart. Our team specializes in diagnosing and treating this condition using the most advanced equipment and techniques. With early detection and diagnosis, arrhythmias can be successfully treated. The goal of treatment is to relieve uncomfortable symptoms and prevent severe complications.

Since the Cardiac Electrophysiology Laboratory at Weill Cornell Medical Center first opened its doors in 1987, it has grown into one of the busiest and most experienced laboratories in the country. Our electrophysiologists have been recognized nationally as leaders in the field through engagement in important research.

Electrophysiology (EP) studies are used to diagnose arrhythmias. During this procedure, catheters (wires) are placed in the heart with X-ray guidance. The heart rhythm is then carefully studied and, if necessary, treated with ablation. Learn more about EP procedure.

Your cardiologist will discuss the diagnosis procedure and all treatments available with you to determine the best option for you.

If you are at risk for arrhythmias (for example, if you have advanced heart disease or coronary artery disease), you may benefit from implantation of electronic devices (implantable cardioverter-defibrillator, cardiac resynchronization devices and pacemakers) into the body to improve the function of the heart and protect against sudden cardiac problems (including death).

The Arrhythmia Service provides:

Diagnostic cardiac electrophysiology studies
Catheter ablation of arrhythmias (including atrial fibrillation, ventricular tachycardia, premature ventricular contractions and supraventricular tachycardia)
Pacemaker implantation
Implantable cardioverter-defibrillator implantation (ICD)
Cardiac resynchronization therapy (bi-ventricular pacing)
Pacemaker and ICD lead removal
Insertable loop recorder (ILR) implantation
Electrical cardioversion
Tilt table testing
Left atrial appendage occlusion and ligation (for stroke prevention in atrial fibrillation patients)
Pacemaker and ICD follow-up clinic
Office consultation for evaluation and management of arrhythmias
Access to research protocols for innovative treatment of heart rhythm disorders

Information for New Patients

To help you and your physician prepare for your visit, please provide the following before scheduling your appointment:

Copies of cardiac-related medical records such as EKGs, Holter or event monitor reports, echocardiograms, stress test, catheterization reports, any MRI or CT scan reports and imaging discs, and any previously performed electrophysiologic procedures. You may also sign this Medical Records Release Form.pdf,and our office will request the records directly.
