摘　　要：目的:探讨心内测定老年人窦房结恢复时间(SNRT)、校正的窦房结恢复时间(CSNRT)和窦房传导时间(SACT)的正常值。方法:对53例无病态窦房结综合征的老年人进行经皮右心房电生理检查,测定其SNRT和SACT。结果:53例老年人SACT98.7±34.4ms(51～222ms);SNRT1058.5±275.7ms(602～2260ms);CSNRT266.1±177.6ms(79～1189ms)。发现SNRT>1500ms,CSNRT>600ms各1例,SACT>150ms者有3例。结论:老年人心内测定的SNRT、CSNRT与文献中食道调搏法测定的无显著差异,而SACT则明显低于食道调搏法(P<0.01),与刺激部位有关。Objective: To explore the normal value of sinus node recovery time (SNRT), corrected sinus node recovery time (CSNRT) and sinoatrial condection time (SACT) in aged person. Methods : Detected the sinus node recovery time and sinoatrial condection time by intra-cardiac assay in 53 cases of aged person without sick sinus syndrome. Results: SNRT was 1058. 5±275. 7 (602-2260) ms, CSNRT was 266.1±177. 6 (79-1189) ms, SACT was 98. 7±34. 4 (51 - 222)ms in 53 aged person. Conclusion: There were no significant difference among SNRT, CSNRT detected by this technique and esophagus frequency modulation in literature, but SACT detected by this technique decreased significantly compared that detected by esophagus frequency modulation.
