  • About Cardiac Arrhythmias

    Our expert cardiac electrophysiologists diagnose and treat all types of arrhythmias, with a full range of medical and procedural options.To make an appointment with an electrophysiologist from the Al-Sabah Arrhythmia Institute, please call 212.523.2400.


    An arrhythmia is any deviation or disturbance in the heart’s normal rhythm. A cardiologist who specializes in heart rhythms, called an electrophysiologist, usually treats this condition. The heart’s normal rhythm is usually well regulated to ensure maximum efficiency and performance. The normal intrinsic pacemaker, called the sinoatrial node, is located in the heart's right upper chamber (atrium), generates the signal or impulse that triggers a heartbeat. The impulse gets to the lower chambers (ventricles) via a specialized conduction system in the heart.  The system is a series of tissues that take the impulse from the top chamber to the lower chamber signaling them to contract. This is what generates a heart beat and pulse.


    Arrhythmias occur when any portion of this sequence is interrupted or disturbed. Arrhythmias may be benign, symptomatic, or even fatal. Their consequences depend not only on their symptoms, but also on the presence of any abnormal structural conditions in the heart.

    Arrhythmia Conditions

    Some examples of arrhythmia conditions treated by an electrophysiologist are atrial fibrillation, bradycardia (slow heart rhythms) and tachycardia (fast heart rhythms). Other conditions that predispose to arrhythmias can be inherited, such as  Long QT syndrome, Brugada Syndrome, and cardiomyopathies.


    The Al-Sabah Arrhythmia Institute at Mount Sinai St. Luke’s has wide-ranging, comprehensive non-surgical and interventional approaches to treat all arrhythmia conditions.

    Our expert cardiologists use diagnostic tests, such as ECG/EKG, Holter monitoring (continuous recording of the heart rate and rhythm over a 24-hour period), event monitoring for problems that may not be found within the 24-hour period, and electrophysiology studies to obtain data about heartbeats and provide important information about arrhythmias, such that they can be treated appropriately.

    The Institute also offers a full spectrum of treatments for arrhythmia conditions, including medications, catheter ablation, and implantation of pacemakers or cardioverter defibrillators (ICDs) and left atrial appendage exclusion techniques to prevent strokes. We also have vast experience with LASER lead extraction, a cutting-edge procedure to safely remove failed or infected pacemaker and ICD leads.
