摘要:
目的 通过电生理标测希氏束、左右束支及其分支的长度 和宽度，明确希浦系统的分布及区域特点，为希浦系统区域起搏提供理论依据。方法 选取行心内电生理检查及 射频导管消融，且无基础心脏疾病的8例患者，逐点标测希氏束电位及左右束支电位，分析并测量：希氏束分布的长度和宽度；左前分支和左后分支分布的长度和宽度；希氏束与最早出现左束支电位的距离。结果 希氏束长度区域为5.4～24.2 mm，平均 15.9 mm；宽度 区域为7.8～11.6 mm,平均 9.6 mm；长度的差异度更明显。左 前分支长度区域为28.8～35.6 mm，平均 31.3 mm；宽度区域为 8.0～17.6 mm，平均 13.1 mm。左后分支长度区域为 22.2～62.1 mm，平均 45.1 mm；宽度区域为 9.4～31.7 mm，平均 13.1 mm。不管是分布长度还是宽度，左前分支与左后分支无统计学差异。希氏束 与左前分支的距离范围为31.8～61.2 mm，平均44.4 mm；到左后分支的距离为 43.0～78.6 mm,平均 59.4 mm。 结论 电生理标测的希浦系统区域远大于希浦系统解剖区域；左束支 分布区域大，在左束支区域起搏可解剖学定位；若以希氏束定位，左束支区域起搏范围建议距离希氏束3.0～4.0 cm。
Abstract:
Objective To determine the distribution and regional characteristics of His-Purkenje system by electrophysiological mapping of the length and width of His bundle,left and right bundle branches and their branches,so as to provide theoretical basis for regional pacing of His-Purkenje system. Methods Eight patients without underlying heart disease who underwent intracardiac electrophysiological examination and radiofrequency catheter ablation were selected. His bundle potential and left and right bundle branch potential were measured point by point. The length and width of His bundle distribution,the length and width of left anterior and left posterior branches,and the distance from His bundle to the earliest left bundle branch potential were analyzed and measured. Results The length of His bundle ranged from 5.4～24.2 mm,with an average of 15.9 mm;the width ranged from 7.8～11.6 mm,with an average of 9. 6 mm.The difference of length is more obvious . The length of left anterior branch was 28.8～35.6 mm,with an average of 31. 3 mm;the width was 8.0～17.6 mm,with an average of 13. 1 mm. The length of the left posterior branch was 22.2～62.1 mm,with an average of 45.1 mm;the width was 9.4～31.7 mm,with an average of 13.1 mm. No matter the length or width of the distribution,there was no significant difference between the left anterior branch and the left posterior branch. The distance from His bundle to left anterior branch was 31.8～61.2 mm,with an average of 44.4 mm;the distance from His bundle to left posterior branch was 43.0～78.6 mm,with an average of 59.4 mm. Conclusion Electrophysiological mapping of the His-Purkenje system is much larger than the anatomical His-Purkenje system;the distribution area of left bundle branch is large,and pacing in the left bundle branch area can be anatomically located;if His bundle is mapping,the pacing range in the left bundle branch area is recommended to be 3.0～4.0 cm away from His bundle
