Paroxysmal atrial fibrillation is a type of AFib that causes short, intermittent episodes of irregular and rapid heartbeats originating in the atria. Cryoballoon ablation is typically used to treat PAF and involves using a balloon catheter to freeze heart tissue and isolate the pulmonary veins that can cause irregular heartbeats.
