Cardiac Electrophysiology

Welcome to the Pacemaker-Arrhythmia Center at NYU Winthrop Hospital

The Pacemaker-Arrhythmia Center at NYU Winthrop Hospital is a state-of-the-art electrophysiology (EP) facility. The center offers cutting-edge services and highly skilled clinical cardiac electrophysiologists who specialize in the entire range of heart rhythm diagnostic and therapeutic procedures.

Our center offers inpatient and outpatient services.

The inpatient facility is located at NYU Winthrop Hospital at 259 First Street in Mineola, NY. This facility consists of 3 dedicated EP laboratories and a separate additional dedicated procedural area for tilt table testing, elective electro-cardioversion, and Implantable Cardioverter Defibrillator (ICD) testing.

Our laboratories and highly trained electrophysiology staff comprise one of the best cardiac electrophysiology facilities on Long Island.

Electrophysiology Procedures

  • Catheter Ablations - A catheter ablation is performed to treat heart arrhythmia, such as rapid or irregular heartbeat. During the procedure, catheters are placed through veins or arteries for pacing, mapping, and recording of electrical signals of the heart. Stimulation of the heart is performed from a specialized control room in which the doctor and staff help to induce and analyze the heart rhythm abnormality (arrhythmia). Once the arrhythmias is determined, it can be treated by delivering energy via the steerable catheters.
  • Device Implantations - Many of the first implants of the latest treatment devices have been implanted in patients at the electrophysiology laboratories of our Pacemaker-Arrythmia Center. Devices to treat all types of heart rhythm disturbances are expertly implanted including pacemakers, implantable cardioverter-defibrillators, implantable loop recorders, and biventricular devices. In addition, laser-lead extraction is performed at our center.
  • Head-Up Tilt Table Testing - This test is performed typically at a 70 degree tilt ("head-up") while the patient's heart rhythm and blood pressure are continuously monitored. Sometimes a medication called isoproterenol is infused to facilitate the test. This test is helpful in determining the cause of syncope and, particularly, in diagnosing vaso-vagal syncope.
  • Cardioversion - This procedure is typically performed to convert atrial fibrillation (or atrial flutter) to a normal rhythm. The staff will require appropriate documentation of anticoagulation and/or a negative trans-esophageal echocardiogram prior to the procedure.

For any procedure, postoperative follow-up should be scheduled with the doctor (or team) that performed the procedure.

Community Service

The NYU Winthrop Team provides a quarterly ICD support group called "The Long Island Miracles." This is a free informative session usually during a weeknight on the NYU Winthrop campus. Key topics related to patient's care or concerns are discussed and refreshments are provided. The schedule can be obtained at 516-663-8530.


NYU Winthrop Electrophysiologists are involved in an active research program. Questions about patient, student or doctor participation should be addressed to 516-663-8530.
