| 摘 要： | 用40 MHz 的射频经静脉导管消融犬心室肌的实验结果表明,40 MHz 的射频可致心肌细胞的局灶性凝固性坏死。坏死周边部用电子显微镜观察,可见部分肌纤维断裂,线粒体中出现许多电子密度增高的颗粒。消融前后血液动力学参数无变化,均未见心律失常和心肌穿孔。初步认为:40 MHz 的射频用于消融心室肌是有效和安全的。

| Abstract: | This article reports the results of catheter ablation of ventricular myocardium in dogs with 40 MHz radiofrequency.The discrete areas of coagulation necrosis were found in myocardium by histo- logical studies.Many granules of high electron density in mitochondria of myocardial cells were found in the border of necrostic myocardium with electron microscocope.No changes were found about hemodynamic states after catheter ablation using 40 MHz radiofrequency,No arrhythmias and perfo- ration of heart were observed also.It is possible that catheter ablation of myocardial tissue using 40 MHz radiofrequency would be considered as safe and effective. |
