Atrial Fibrillation Ablation Procedure | MedStar Health

Stopping faulty electrical signals in the heart

Ablation is an option to treat atrial fibrillation (AFib). We may use this procedure if other treatments aren’t enough to improve your symptoms.

The doctors in our Electrophysiology program are national leaders in the use of cryoablation, or cold therapy, for treating atrial fibrillation. This option can be less painful for patients and is less likely to affect healthy heart tissue. Our expertise with arrhythmia management allows us to treat even the most challenging cases that may not have responded to other approaches.

What are the available atrial fibrillation ablation options?


Sick sinus syndrome

Sick sinus syndrome is a malfunction of the heart’s sinus node, which controls heart rhythms. This causes the heart to beat too quickly or too slowly or leads to long pauses between heartbeats.

Tachycardia-bradycardia syndrome

Tachy-brady syndrome is a type of irregular heartbeat in which the heart fluctuates between beating too quickly and too slowly.



An echocardiogram uses high-frequency sound waves to create images of your heart.

Electrocardiogram (ECG)

An electrocardiogram, also known as an ECG, measures the heart’s electrical activity.

Stress tests

Stress tests are used to assess how your heart works during physical activity. There are several types of stress tests, including treadmill or bike stress tests, nuclear stress tests, stress echocardiograms, and chemically induced stress tests.
