本文测定41例心动过缓病人的窦房结恢复时间(SNRT)。并与阿托品试验进行对比。结果表明SNRT的测定,对病态窦房结综合征(简称病窦)具有较高的诊断价值。阿托品试验(2mg)结果与SNRT的测定相比,符合率为85%,值得临床推广应用。病窦组12例SNRT全部延长,窦缓组29例中,12例延长,17例正常。阿托品试验与SNRT对比分析发现:当使用1mg阿托品时,阿托品试验阴性的7例,无一例SNRT超过正常,阴性符合率为100%。但阿托品试验阳性的27例,只有19例SNRT超过正常,阳性符合率为70.4%。当使用
In this paper, 41 cases of bradycardia in patients with sinus node recovery time (SNRT). And compared with atropine test. The results show that the determination of SNRT for sick sinus syndrome (referred to as sick sinus) has a high diagnostic value. Atropine test (2mg) results and SNRT determination, the coincidence rate of 85%, worthy of clinical application. The SNRT was prolonged in all 12 cases of sinusitis group, while in 29 cases of sinus delay group, 12 cases were extended and 17 cases were normal. Atropine test and SNRT analysis found that: when using 1mg atropine, atropine test negative in 7 cases, no case of SNRT more than normal, the negative coincidence rate of 100%. However, in 27 cases with positive atropine test, only 19 cases had SNRT over normal, and the positive coincidence rate was 70.4%. When used
