Electrophysiology

About Electrophysiology

Electrophysiology (EP) is a cardiac specialty that studies electrical activity in the heart to determine if there are any disturbances in the heart's rhythm, which controls the body's electrical system and maintains good blood circulation.
North Shore-LIJ is proud to be on the forefront of cardiac care with regionally and nationally recognized electrophysiology specialists that are committed to treating the full spectrum of heart rhythm disorders.
Treatments are based on the needs of each patient and will be discussed on an individual basis. Therapies and treatments for abnormal heart rhythm can include the following:

  • Lifestyle management
  • Medications
  • Electronic devices to control heart rhythm including pacemakers and defibrillators
  • Ablations for atrial fibrillation, supraventricular tachycardia and ventricular tachycardia
  • Devices for heart failure
  • Noninvasive tests and procedures such as cardioversions, tilt table testing, heart monitoring

If you have an abnormal heart rhythm and would like to schedule an appointment with an Electrophysiologist, call (855) HEART-11.

Treatment Innovations

The advanced electrophysiology laboratories at North Shore-LIJ Health System use the latest diagnostic and treatment technologies to improve patient care and outcomes. Some of the more recent EP advancements include:

  • MRI Safe Pacemaker
    • The health system was one of the first to offer patients a pacemaker that can be safely used during certain magnetic resonance imaging (MRI) scans. Before then, patients with pacemakers were unable to have an MRI because it could interfere with the functionality of their pacemaker.
  • Cryoablation Catheter Ablation
    • Southside Hospital in Bay Shore was the first hospital on Long Island to perform a cryoablation, a minimally invasive procedure that uses a cold application to treat an arrhythmia instead of the traditional heat application – reducing the complexity of the procedure and radiation exposure.

In the near future, North Shore-LIJ will offer patients a breakthrough implantable device that blocks blood accumulation in the heart's left atrial appendage. This will be a potential alternative to blood thinners to prevent stroke causing clots – a significant advancement and for many cardiac patients..
