洋地黄自从1785年问世以来,至今仍是慢性心力衰竭治疗时最常使用的强心药物。但是,对洋地黄长期疗法持续有益的效应却仍有争论。本文报告9例慢性充血性心力衰竭呈正常窦性心律的患者,在洋地黄持续口服时、停药后和再次静脉给药时所发生的血液动力学改变。部分病例并通过门电路血池闪烁照相评价洋地黄长期疗法对左心室喷血分数的影响。方法:慢性充血性心力衰竭患者9例,年龄
Digitalis since its inception in 1785, is still the most commonly used in the treatment of chronic heart failure cardiac drugs. However, the continuing beneficial effects of long-term treatment of digitalis remain controversial. This article reports on the hemodynamic changes in nine patients with normal sinus rhythm in patients with chronic congestive heart failure, with continuous administration of digitalis, withdrawal and re-administration of digitalis. In some cases, door blood circuit was used to evaluate the effects of digitalis long-term therapy on left ventricular ejection fraction. Methods: Nine patients with chronic congestive heart failure, age
