If you have an irregular heartbeat (commonly known as an arrhythmia), your heart may feel as if it flutters, skips a beat or beats out of rhythm. Left untreated, some types of arrhythmia can lead to fainting and falls, strokes or sudden death. Atrial fibrillation, or AFib, is the most common of the many types of arrhythmia.
The Frank P. Tourville Sr. Arrhythmia Treatment Center at MUSC Health has South Carolina’s most experienced team of arrhythmia specialists. Our electrophysiologists (heart rhythm experts) are recognized nationally and internationally for their clinical expertise in treating AFib and other types of arrhythmia.
As the only academic medical center in South Carolina, our doctors offer arrhythmia treatment options not available elsewhere in the state. Through comprehensive, personalized care, they find the cause of an irregular heartbeat and recommend treatments to resolve it. At the Arrhythmia Treatment Center, you will find:
MUSC Health has been recognized as High Performing in Heart Arrhythmia treatment in the 2025–2026 U.S. News & World Report rankings. This distinction demonstrates our expertise in diagnosing and treating complex rhythm disorders with precision and care.
*The highest VT program in the Southeast and among the highest volumne programs nationally.
Arrhythmia is a problem with the heart’s wiring — its electrical system. The doctors who treat arrhythmia are electrophysiologists, sometimes called the electricians of the heart.
MUSC Health is a pioneer in advanced heart mapping, which is like a GPS to direct our doctors to heart problems. Our EP doctors use the latest mapping systems to track the heart’s electrical function to identify and treat arrhythmia. MUSC Health has been a leader in developing and using new arrhythmia-mapping tools that:
Mild arrhythmia may be treatable with medications or a one-time procedure that shocks the heart into rhythm, called electrical cardioversion. For many people, the best solution to arrhythmia is heart ablation. This minimally invasive procedure eliminates electrical pathways that cause an irregular heartbeat.
Arrhythmia treatments at MUSC Health include:
Our team offers advanced treatments for arrhythmia and AFib, including subcutaneous implantable cardiac defibrillators (ICDs), which an MUSC Health doctor helped develop. See our arrhythmia devices.
Our heart rhythm experts use ablation to correct simple or complex arrhythmias, including those that previous attempts have not successfully reduced. We perform catheter ablation in our dedicated EP labs, with special equipment to test your heart’s electrical activity.
In catheter ablation, doctors guide catheters (thin wires) through a blood vessel in your neck or groin to reach your heart. The catheter sends energy in the form of heat (radiofrequency ablation) or extreme cold (cryoablation) to destroy small areas of tissue that are causing irregular heart rhythms.
We offer two specialized forms of ablation:
Electrical cardioversion delivers an electrical shock to your heart. This minimally invasive procedure resets your heart to a normal rhythm by disrupting the impulses causing the arrhythmia.
About electrical cardioversion:
If you have mild arrhythmia symptoms, medications may help. Your doctor may prescribe more than one medication or try different doses to find the right combination and dosage to get your symptoms under control.
