摘　　要：对５０例胃镜术前、术中患者进行了心电图连续观察，结果发现：术中①窦性心动过速发生率１００％；②心律失常（室性或／和房性早搏）发生率２８％；③Ｔ波压低或倒置发生率１９％～７２％。胃镜插至咽部、食道左房段和呃逆时上述变化发生率高。这些变化均为一过性，停止胃镜检查后自行消失。提示：胃镜检查时突然心率增加或伴心律失常，心肌耗氧量势必增多，有器质性心脏病人尽量不做胃镜检查，以免诱发恶性心律失常或猝死。Electrocardiograms were observed continually in 50 cases before and during gastroscopy.The results demonstrated that(1)sinus tachycardia occurted in all patients;(2)the incidence of arrhythmia(ventricle or/and atrial premature beat)was 28%;(3)T wave depression or inversion amounted to 19%～72%.The abnormalities of ECG were frequent while gastroscope was inserted to the site of the pharynx and beneath the left atrium,or while the patients hiccuped.These changes of ECG were transient.They would disappear automatically after gastroscopy.It indicated that myocardial oxygen consumption had to increase as a result of tachycardia or arrhythmia during gastroscopy.The patients with organic heart diseases should not undergo this examination so as to prevent malignant arrhythmia or sudden death.
