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5min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、柬支传导阻滞，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〉0．1mV发生率为17．05％，与检查前和检查后5min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5min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（X^2=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。Objective To study the electrocardiographic changes in patients undergoing colonoscopy. Methods Continuous electrocardiographic recording was conducted for patients undergoing colonoscopy （n=88）. Results Arhythmia occurred during colonoscopy included sinus tachycardia, sinus bradycardia, premature vetricular contraction, premature atrial contraction, supraventricular extrasystoles, supraventricular tachycardia, bundle branch block, T wave flattening or inversion and S-T segement depression. The ratio of arrhythmia and ischemic S-T segment during the examination in patients who had arrhythmia before were significantly higher than those who did not （X^2= 10.91--30.89,P〈0.01）. Conclusion Colonoscopy can cause transient arrhythmia and possesses potential risk for patients with cardiac diseases. A corresponding monitoring should be given to them.
