An instrument and technique have been devised for the production of complete atrioventricular heart block in anesthetized, closed-chest animals. The instrument is inserted into the right atrium via the right external jugular vein. Localization of the atrioventricular node region by the visualization of intracardiac landmarks with fluoroscopy makes electrical recording unnecessary. Discrete injections of a radiopaque necrosing solution produces the heart block. Procedure time is under 30 min a success rate of 90%.
已设计出一种仪器和技术，用于在麻醉的闭胸动物中产生完全性房室传导阻滞。该仪器通过右颈外静脉插入右心房。通过荧光透视观察心内标志来定位房室结区域，无需进行电记录。离散注射不透射线的坏死溶液可产生心脏传导阻滞。手术时间在30分钟以内，成功率为90%。
