Progress of Frequency Ablation Technique on Atrial Fibrillation Treatment / 中国医疗器械杂志

Atrial Fibrillation(AF) and its complications are serious threat to human health and the radio frequency ablation (RFA) becomes one of the main therapies of AF. Conventionally, the RFA is performed by unipolar ablation mode. Because the unipolar ablation mode is point-to-point and incomplete linear lesion formation, the success rates of treatment on AF decline and the procedures are time consuming. In order to solve these shortcomings, the bipolar ablation mode and the multichannel frequency ablation method that facilitate the easy creation of linear lesion are presented, especially kinds of multichannel frequency ablation technique and applications are introduced in this paper.
