动态心电图等三种方法对窦房结及房室结功能诊断价值的再探讨

To reapproach value of dynamic electrocardiogram etc.three examinations in diagnosing function of sinoatrial node and atrioventricular node

目的再评估动态心电图、阿托品试验及其前后食管调搏检测对窦房结及/或房室结功能的诊断价值。方法观察35例经动态心电图检查符合病态窦房结综合征的上述检查结果。结果7例食管调搏正常及阿托品试验阴性 ;6例阿托品试验阳性 ,其前后食管调搏均异常 ;17例阿托品试验前食管调搏异常 ,阿托品试验后恢复正常。结论以上检查对诊断窦房结及/或房室结功能障碍各有不同的意义 ,应结合临床表现联合应用以提高正确诊断率。

Objective To reapproach value of dynamic electrocardiogram,atropine test and eximination of transesophageal atrial pacing before and after atropine test in diagnosing function of sinoatrial node(SAN) and atrio_ventricular node(AVN).Methods To observe 35 catients with sick sinus syndrome diagnosed by dynamic electrocardiogram and examine result with afore_said methods.Results 7 cases showed normal of transesophageal atrial pacing and atropine test negative;6 cases showed atropine test positive and examination of transesophageal atrial pacing abnormal both befor and after of atropine test positive17 cases showed consequence of transesophageal atrial pacing examination were abnormal before atropine test and restored to normal after atropine test.Conclusion Aforementioned examination each had his different meaning in diagnosing dysfunction of sinoatrial node and atrio _ ventricular node and both.Three methods should be combined in using so diagnose more correctly.
