本研究旨在介绍在左室以射频能量进行导管消蚀房室交界区的新技术。8例药物治疗无效的顽固性室上速患者,年龄51±19岁。房室结折返性心动过速3例,使用隐匿性中间隔旁道的房室折返性心动过速、房性心动过速及房颤各1例,房扑2例。以射频能量在右侧行导管消蚀房室结(6例)或以射频能量及直流电击消蚀房室结(2例)均未成功。频率为350kHz的射频能量以连续的非调制正弦波发放。释放射频电流经由7F四极导管,其顶端电极长4mm,电极间距5mm,
The aim of this study is to introduce a new technique for catheter ablation of the atrioventricular junction in the left ventricle with radiofrequency energy. Eight patients with refractory and refractory supraventricular tachycardia were 51 ± 19 years of age. Atrioventricular nodal reentrant tachycardia in 3 cases, the use of occult bypass in the atrioventricular reentrant tachycardia, atrial tachycardia and atrial fibrillation in 1 case, atrial flutter in 2 cases. Radiofrequency catheter ablation in the right atrioventricular node (6 cases) or RF energy and DC shock atrioventricular node (2 cases) were unsuccessful. RF energy at 350kHz is delivered as a continuous, non-modulated sine wave. Release of RF current through the 7F quadrupole catheter, the top electrode length 4mm, the electrode spacing 5mm,
