Conclusion : Radiofrequency catheter ablation is of significant clinical value in the treatment of " fast slow " supraventricular arrhythmias. 结论:射频导管消融法治疗“快&慢”型室上性心律失常具有重要的临床价值。
Radiofrequency Catheter Ablation of Fast Slow(FS) Supraventricular Arrhythmias and Follow up 快-慢型室上性心律失常的射频导管消融治疗及随访
CONCLUSION Patients with residual slow pathway conduction, and larger fast slow pathway ERP difference, AVN echo beats, after ablation, without accelerated junctional tachycardia during radiofrequency application are at higher risk of recurrent AVNRT. 结论射频消融房室结慢径后存在残余慢径传导,出现房室结回波,释放射频能量时无加速性结性心动过速及残余慢径有效不应期长与复发AVNRT有关。
Wheat cultivars of different genotypes selected from different places showed in a three year experiment a common law in their milking stage that the accumulation of dry material during this stage was done at a slow fast slow speed, in accordance with a " S " type distribution. 选用各地不同基因型小麦品种,经三年连续试验,初步揭示出不同品种在灌浆期的共同规律:籽粒干物质累积按慢快慢(FS)顺序,呈s形分布;
The fast and slow waves can both propagate in the waveguide system. 快波和慢波都可以在这种波导中传播。
