目的探讨阿托品试验改良法对窦房结功能的诊断价值。方法取2008年6月至2009年9月在我院行阿托品试验的患者,均经其他检查(动态心电图或心电图)诊断为窦性心动过缓,共220例。分为常规组和改良组,行阿托品试验。结果常规组阳性33例,占30.5%,改良组阳性16例,占15.7%。结论常规阿托品试验法存在一定的假阳性,阿托品试验改良法可减少假阳性,可提高对窦房结功能的诊断价值。
Objective To investigate the diagnostic value of modified atropine test for sinus node function. Methods From June 2008 to September 2009 in our hospital atropine test patients were diagnosed by other tests (ambulatory ECG or ECG) sinus bradycardia, a total of 220 cases. Divided into the conventional group and the improved group, line atropine test. Results In the conventional group, 33 cases were positive (30.5%), and 16 cases (15.7%) in the modified group. Conclusion Conventional atropine test method has some false positives. Atropine test improved method can reduce the false positive and improve the diagnostic value of sinus node function.
