Arrhythmia Treatments at Mount Sinai

Mount Sinai's Center for Electrophysiology offers the full range of proven and emerging treatments for all types of arrhythmia, from common atrial fibrillations to challenging ventricular tachycardias. Our electrophysiologists—cardiologists who specialize in treating arrhythmias—are skilled in performing the full spectrum of therapies, which includes procedures to fix the heart tissue causing the abnormal heartbeat (called ablations), implantable devices (such as pacemakers and defibrillators), and medications (such as blood thinners and anti-arrhythmia drugs). In addition, our treatment options are continually expanding, as we regularly start new research studies—which means our patients have access to the most advanced therapies in the form of clinical trial enrollment.

When determining the best course of treatment, our cardiologists consider each patient's personal and medical background, including factors such as the frequency and seriousness of the arrhythmia, the patient's risk of stroke, underlying cause of the arrhythmia, presence of other problems (such as coronary artery disease or valve disorders), the patient's use of medications taken for other conditions, age, and overall health.

Based on these factors, as well as state-of-the-art diagnostic tools (such as electrocardiograms, imaging studies, and prolonged monitoring), our physicians will talk to you about pursuing one or a combination of treatments. 

Treatment Options for Arrhythmia

Mount Sinai electrophysiologists are skilled in administering the following arrhythmia treatments to return the heart to its regular rhythm.

Catheter Ablation Procedures for Atrial Fibrillation

In a catheter ablation procedure, a thin tube is threaded to the areas of the heart that are causing the arrhythmia, where it delivers a surge of energy in order to scar the problematic tissue.

Medications for Managing Arrhythmias

Medications used to treat arrhythmias include blood thinners and anti-arrhythmia medications.

Left Atrial Appendage Procedures

Patients who can't tolerate medications may be considered for a left atrial appendage procedure that isolates the part of the heart where blood is most likely to clot so that the clot cannot enter the blood stream.

Implantable Devices

Devices (such as pacemakers and defibrillators) maintain the heart's rhythm, as well as record the heart's function so that physicians can monitor a patient's condition.


In some instances, brief bursts of electricity can correct abnormal heart rhythms. While the patient is sedated, cardioversion physicians use a cardioverter machine to deliver electrical pulses to the heart. This procedure can treat different types of abnormal rhythms but is not a cure.
