Establishment of intraoperative diagnostic method using simple electrophysiological study and development of lower invasive surgical procedure including endoscopic surgery for chronic atrial fibrillation

(1)我们研制了一种独特的电极，它是通过负压固定在心房上，用于术中房颤时心房电位的同步分析。一个电极在矩形垫上具有74个单极电极，另一个电极在线性垫上具有10个单极电极。(2)我们进行了简化的程序，已修改了考克斯迷宫沿着我们的临床和电生理经验的慢性心房颤动。该手术包括神经节丛的去神经支配。我们分析了该手术的临床结果。

(1) We have developed a unique electrode which is fixed by negative pressure on the atrium for simultaneous analysis of the atrial potential during fibrillation intraoperatively. One electrode has 74 unipolar electrodes on the rectangular pad and another has 10 unipolar electrodes on the linear pad. (2) We have performed simplified procedure which have been modified from Cox maze along with our clinical and electrophysiological experience for chronic atrial fibrillation. This procedure included a denervation for ganglion plexus. We analyzed the clinical outcomes of this procedure.
