[Catheter ablation--new cure for paroxysmal atrial fibrillation. Case reports show how the trigger mechanism can be abolished].

Abstract

The trigger mechanism of paroxysmal atrial fibrillation is usually an atrial ectopic beat originating in the muscular sleeves of the pulmonary veins. These and other origins of the trigger mechanisms can be explored with electroanatomical mapping technique. Once identified, the trigger mechanism may be abolished by using the catheter ablation technique to cure the arrhythmia. We present the results for two patients with trigger mechanisms of different origin whose arrhythmia has been cured using the focal ablation technique.
