Heart Rhythm Disorders

Each time your heart beats – typically 50 to 100 times a minute– it’s working to pump and circulate blood throughout the body. This process requires all the parts of your heart to be functioning properly, following the heart’s usual rhythm. However, when the heartbeat becomes irregular or uneven, this is called an arrhythmia.

There several different types of arrhythmia, all of which have unique causes, symptoms and can range in severity. In some cases, an arrhythmia may cause your heart to beat too slow (bradycardia) or too fast (tachycardia), while others may cause it to beat irregularly. This is the case for atrial fibrillation (AFib), the most common form of arrhythmia, which currently affects more than 2.2 million Americans.

Why Choose The Heart Center of NGMC?

In some cases, an arrhythmia can be harmless and silent, meaning they cause no symptoms. Other times, an arrhythmia can be extremely dangerous, even an emergency. The only way to really know is to work with a cardiologist that’s specifically trained to care for arrhythmias, known as an electrophysiologist.

As one of the top electrophysiology programs in the state, The Heart Center of NGMC provides the highest level of diagnostics and treatment for nearly every type of heart rhythm disorder.

Led by our fellowship-trained electrophysiologists, our program offers a full spectrum of services, including some of the most cutting-edge treatments, like device implantation and magnetic-guided catheter ablations. We perform all of our electrophysiology procedures in the state-of-the-art cardiac catheterization labs at NGMC Gainesville and NGMC Braselton.

Heart Rhythm Disorders We Treat

While there are many different types of arrhythmias, they are primarily identified and categorized based on two different criteria – what part of the heart they’re in and what affect they have on the heartbeat. We are able to detect, diagnose and treat arrhythmias that fall into each of these categories, including:

Atrial Fibrillation (AFib)

This is when the heart’s upper and lower chambers fall out of coordination with one another, causing the heartbeat to become fast and erratic. AFib is the most common type of arrhythmia, but it can also be one of the most dangerous, increasing your risk for blood clots, stroke and heart failure.

Atrial Arrhythmia

Also known as supraventricular arrhythmia, this type occurs in the upper chambers of the heart, known as the atria. In addition to AFib, there are several different forms of atrial arrhythmia, including supraventricular tachycardia (SVT) and atrial flutter.

Ventricular Arrhythmia

This type occurs in the lower chambers of the heart, known as the ventricles. A few specific types are ventricular tachycardia (V-tach) and ventricular fibrillation (V-fib). Ventricular arrhythmias can be life-threatening and require immediate medical attention.

Electrophysiology Services at The Heart Center

When you receive arrhythmia treatment at The Heart Center of NGMC, every part of your care is strategically coordinated to ensure the best possible experience and outcome. This starts with in-depth diagnostics and testing that our experienced electrophysiologists use to shape treatment and care that’s targeted and precise.

Our specialized services and treatments, include:

WATCHMAN (Left Atrial Appendage Closure)

This is a specific kind of implantable device designed to reduce the risk for stroke in patients living with AFib. Using a transcatheter approach, the WATCHMAN is guided to the part of the heart most likely to form blood clots and closing it off to prevent future clots from escaping. Learn more.

Implantable Cardioverter Defibrillator (ICD)

An ICD is a small, battery-powered device that’s implanted in your chest and used to monitor your heartbeat. If an abnormal rhythm is detected, it can help correct it by sending an electrical shock to your heart.

Radiofrequency Catheter Ablation

Also known as catheter ablation, this minimally-invasive procedure uses radiofrequency energy to target the heart tissue that’s causing the arrhythmia. Once the abnormal tissue is destroyed, this helps restore your heart’s regular and healthy rhythm.


Using a transcatheter approach, a cryoprobe is guided to the area of the heart causing the arrhythmia. It then uses extreme cold temperatures to remove the abnormal tissue. Cryoablation is one of the most cutting-edge forms of treatment and is often safer and easier than other forms of ablation.

Electrophysiology Study

This is a specialized diagnostic procedure used to gather data and inspect the heart’s electrical function. Using a catheter with electrodes, your electrophysiologist is able to assess the heart’s rhythm, speed and pattern. In some cases, they may trigger an episode or arrhythmia to gain greater insight into your specific condition.

Cardiac Resynchronization Therapy

Similar to an ICD, cardiac resynchronization therapy (CRT) uses a small, implanted pacemaker to monitor the heartbeat and to detect any abnormalities. In the event that the device senses an abnormal rhythm, it uses electrical pulses to correct it. CRT is used to meet the unique needs of patients living with both an arrhythmia and heart failure.
