Arrhythmia Center


About 4 million Americans suffer from arrhythmia, including many younger people. Arrhythmias are extremely common, especially as you get older.

Most cases are harmless, but there are some cases that are dangerous and require treatment and management.

Arrhythmias are also more serious if you have other heart problems, or have had prior heart attacks.

(L-R) Grant Simons, MD, Director of Cardiac
Electrophysiology, David Feigenblum, MD and
Dmitry Nemirovsky, MD have performed over 400
atrial fibrillation ablation procedures.

Many people have experienced rapid heartbeats, “skipped beats”, or “fluttering” in their chest. These changes can be brought on by exercise, emotion, stress, and caffeine among other things, and are usually not a cause for alarm. Arrhythmias that occur frequently or cause severe symptoms such as dizziness, chest pain, passing out, or shortness of breath should be discussed with a doctor.

At Englewood’s Arrhythmia Center, we also use advanced computer mapping systems to see real-time images of the electrical activity within a patient’s heart. These new mapping technologies include phased-array intracardiac ultrasound and both contact and non-contact mapping, all of which improve the efficacy of diagnosis and safety of subsequent treatment. This information is used to pinpoint the location of normal and abnormal heartbeats – information vital to treating arrhythmias.

In addition, Englewood’s Arrhythmia Center is one of the few centers that treat atrial fibrillation with "catheter-based" procedures -- those that utilize long flexible wires to enter the heart in an attempt to stop the arrhythmia at its source. In many cases, this emerging technology literally cures this troublesome arrhythmia. We also are one of the few centers in the tristate area to use cryoablation for the treatment of certain arrhythmias. We also provide the latest implantable devices for those patients who need them.

We also utilize the latest in robotic catheterization and surgery. Our robotics program, which includes the use of the  Sensei® Robotic Catheter System for cardiac arrhythmia, is discussed in depth here.
