Atrial fibrillation is an irregular heart rate that can increase the risk of other heart-related complications. Symptoms of atrial fibrillation include dizziness, shortness of breath, and fatigue. Atrial fibrillation also increased the risk of stroke. A new treatment used at Mayo Clinic called cryoablation can aid in the treatment of atrial fibrillation. During the procedure a catheter is inserted into the area of the heart with the arrhythmia and a balloon is deployed freezing the area causing the atrial fibrillation.
