作者综述文献指出,使用洋地黄时心电图所显示的改变,大多没有把洋地黄对心电图的影响和心肌缺血本身造成的心电图改变区别开来。为此,作者探讨健康心脏在洋地黄作用下是否会出现病理性ST段压低。方法:49名(男46,女3,平均年龄24.4±2.5岁)临床和实验室检查无心、肾、肺疾患者在基础检查后,给予静脉缓慢注射地高辛1.5毫克,24小时后再静脉注射1.25毫克,注射完毕24小时后作第二次检查,包 The authors summarize the literature that most of the changes shown by electrocardiography with digitalis do not distinguish between the effects of digitalis on the electrocardiogram and the electrocardiographic changes caused by myocardial ischemia itself. To do this, the authors investigated whether a healthy heart under pathologic digitalis would have pathologic ST-segment depression. Methods: 49 (male 46, female 3, mean age 24.4 ± 2.5 years) clinical and laboratory examinations of patients with no heart, kidney and lung disease were given a slow intravenous injection of 1.5 mg of digoxin after a basal examination. After 24 hours, intravenous 1.25 mg injection, 24 hours after injection for the second check, package
