Cardiac Arrhythmia Service

Dec 1, 2016Posted by nameless

Our Approach

At the Cardiac Arrhythmia Service at Renai Hospital Heart Center, our specialists are experienced in treating a range of heart rhythm conditions, including:

Arrhythmias (abnormal heart beat)

Atrial fibrillation

Atrial flutter

Supraventricular tachycardia

Ventricular fibrillation

Ventricular tachycardia

Brugada Syndrome (genetic condition)

Long QT Syndrome (genetic condition)

Bradycardia (slow heart rate)

Sick sinus syndrome (heart rate too fast and too slow)

A team of electrophysiologists, nurses, technologists, research staff, cardiac resynchronization therapy specialists and holter monitor specialists make up the Cardiac Arrhythmia Service and Electrophysiology Lab.Our specialists treat a variety of patients, including younger and older patients, pregnant women with arrhythmias, patients with atypical symptoms or unique conditions, patients with familial conditions, and patients who require pacemakers, ICDs or biventricular devices. We also treat patients with atrial fibrillation and have revolutionized medical care for this condition.

Diagnosing Cardiac Arrhythmias

Cardiac arrhythmias can be diagnosed using non-invasive procedures or invasive procedures such as electrophysiology (EP) studies. Our specialists offer the latest diagnostic procedures for all cardiac arrhythmias. Your doctor may order one or more of these tests for you.

Electrocardiograms, including signal-averaged electrocardiography

Holter monitoring

Event recorder


Exercise test (stress test or treadmill test)

Tilt table evaluation

Invasive electrophysiology studies

Leading Treatments and Procedures

With advanced resources, including leading-edge technology in the hands of experienced clinicians, the Cardiac Arrhythmia Service offers several options to help manage arrhythmias. Specialists at the Cardiac Arrhythmia Service evaluate and recommend the best treatment plan for patients. Available treatments include:

Antiarrhythmic medications

Arrhythmia genetics clinic

Implantable cardioverter defibrillators (ICDs) and pacemaker insertion

Catheter ablation, including cryoablation and radiofrequency ablation

Cardiac resynchronization therapy (CRT)

Electrical cardioversion

Complicated ablation procedures and pulmonary vein isolations

About This Program

Physicians within the Cardiac Arrhythmia Service at Renai Hospital Heart Center are internationally recognized for their work in the field of clinical electrophysiology, the medical discipline concerned with the heart's electrical system. Rencent years, the Cardiac Arrhythmia Service has provided state-of-the-art care for patients with all types of cardiac arrhythmias. Our experienced specialists work with all types of patients to determine the cause of their heart rhythm disturbances, develop a plan of care, and monitor progress and response to treatment. Though in many cases, we can cure cardiac arrhythmias; in other cases, treatment is focused on reducing or eliminating symptoms.

Sophisticated Treatments

A Leader in Treating Atrial Fibrillation. Every year our physicians host Atrial Fibrillation Symposium.

This symposium is a forum for discussing the latest research and ways to manage atrial fibrillation.

Learn how physicians at the Cardiac Arrhythmia Service treat atrial fibrillation

Specialists at the Cardiac Arrhythmia Service were among the first physicians in the world to use a computer-based robotic system that helps specialists ablate (destroy) small areas of heart muscle tissue that are responsible for common cardiac arrhythmias. This revolutionary technology enables our specialists to treat patients with greater precision, safety and effectiveness than was previously possible.

Our physicians also helped establish a new catheter ablation procedure for the treatment of atrial fibrillation, the most common kind of cardiac arrhythmia. Catheter ablation delivers a radio frequency current through a catheter tip to prevent electrical impulses from traveling through the heart's tissue at the site of the arrhythmia. This new therapy has helped eliminate disabling symptoms and restore quality of life for many patients with atrial fibrillation.

A Commitment to Research and Education

Physicians at Renai have revolutionized medical care for cardiac arrhythmias. All over the world, other clinicians are able to better treat atrial fibrillation through image integration, a technology we helped develop that blends high-quality images of a patient's anatomy into the actual procedure.

Many of our physicians are on the faculty of Medical School, which means they not only have a mission to provide the best possible patient care, but also a commitment to educate the next generation of medical professionals.

Conditions and Diseases

The care team at the Renai Heart Center encourages all patients and family members to learn more about conditions and diseases that affect the heart and overall cardiovascular system. The links below provide more information about heart conditions and diseases that might be treated within this program.


Arrhythmias are heart rhythm disorders that may originate in the atria (the receiving chambers of the heart) or the ventricles (the pumping chambers of the heart).

Atrial Fibrillation

Atrial fibrillation is a type of arrhythmia where the electrical signals in the atria (the two small chambers of the heart) are fired in a very fast and uncontrolled manner.
