摘　　要：目的　观察急性下壁心梗时 ,心电图检查和希氏束检查房室传导阻滞发生的时间和对预后的影响。方法　患者 2 4例 ,分为 :(1)单纯下壁组 ;(2 )下壁后壁或右室组 ;(3)下壁合并前、侧壁组。均行心电图及希氏束电图检查。结果　三组房室传导阻滞发生率相似 ,多数房室传导阻滞在急性心肌梗死起病后 12h内出现 (81 8% )。阿托品和异丙肾上腺素治疗 14例 ,AVB都有不同程度的改善 ,预后良好。结论　急性下壁与合并其他部位心梗的AVB发病率相似 ,大部分出现时间为 12h以内 。Objective To evaluate relationship between the occurrence time of AV block in acute inferior myocardial infarction and its prognosis.Methods With ECG examination and cardiac electrophysiologic techniques,24 patients were divided into three groups:inferior group,myocardial group,right ventricle group,inferior and lateral group.Results The rate of AV block in three groups were similar.The majority of AV block appeared 12 hours after the onset of acute myocardial infarction.14 patients treated with atropine and isopropylarterenol,AV block degrees were improved,and the prognosis was weel.Conclusion The occurrence rate of AV block in acute inferior myocardial infarction is similar to those in other sites.The majority of AV block appear 12 hours after onset of AMI,and the prognosis is good.
