心内电图提示人类Ⅰ型房扑是由右房内额面的逆钟向旋转的大折返环引起。慢通道区域位于右房后间隔下部,包括在三尖瓣环和下腔静脉之间的心房组织的峡部中。先前的研究显示了应用射频电流于此峡部组织进行消融能够终止房补。本研究观察预测射频 Cardiac electrocardiogram prompted human type Ⅰ atrial flutter is caused by the face of the right atrium in the face of the inverse rotation of the bell reversal ring caused. The slow aisle region is located in the lower right atrioventricular septum, including in the isthmus of atrial tissue between the tricuspid annulus and inferior vena cava. Previous studies have shown that the application of RF current in this isthmus ablation can terminate atrial fibrillation. This study observes the prediction of radio frequency
