Depending on the situation, your physician may recommend cryoblation. By freezing the tissue or heart pathways that interfere with your normal heart rhythm, the cells that are responsible for the arrhythmia are altered so they can't conduct impulses.
Cryoablation therapy is a non-surgical, minimally invasive procedure. A catheter with a cooling tip subjects the cells to sub-zero temperatures that isolate or destroy the tissues that are causing atrial fibrillation.
