[摘要]目的 探讨结肠镜检查过程中病人心电图的变化。方法 采用12导联同步监护方法，监测88例行结肠镜检查病人结肠镜术前、术中及术后5 min心电图的变化。结果 结肠镜术中出现的心律失常以窦性心动过速、窦性心动过缓、室性期前收缩、房性期前收缩、阵发性室上速、束支传导阻滞，ST-T改变以T波低平及ST段压低为主，结肠镜头端途经肝区及回盲部时心率增高，但与检查前比较差异无显著性;结肠镜术中ST段水平或下斜型压低>0.1 mV发生率为17.05%，与检查前和检查后5 min比较差异无显著性;结肠镜术前即有心律失常和ST段阳性改变组结肠镜术中及术后5 min心律失常发生率和ST段阳性改变率明显高于术前无心律失常和无ST段阳性改变组( χ2 =10.91～30.89，P 均<0.01)。结论 结肠镜术中出现的心电图改变是短暂的、一过性的，但对心脏病病人有潜在危险性，应给予相应的监护以及早发现。
