Recent Advances in Radio Frequency Ablation Techniques of Atrial Fibrillation

Multiple wavelet hypothesis and fibrillatory conduction are believed to be atrial fibrillation's pathogenesis. Radio frequency ablation(RFA) technique, a therapy for atrial fibrillation(AF), applies radio frequency(RF) energy to targeted tissue to make it transmural. Research on AF ablation has already been conducted in China. Currently, there are single-electrode and dual-electrode ablation electrodes. It is discovered that the latter can reduce the treatment time and maintain the ablation shape of the tissue. Clinical application has shown that it has become the first-line treatment option for part of indications patients with AF.
