近年来,应用心得安(β受体阻断剂)鉴别器质性与功能性心电图 ST—T 改变,国内外屡有报道,此项检查称为心得安试验。心得安试验阳性,说明患者存在交感神经兴奋性增高,可为心得安所拮抗,此乃多见于心脏神经症(包括β受体高敏状态);心得安试验阴性,则提示患者的 ST—T 改变不能通过心得安以消除,多见于冠心病、心肌炎等器质性心脏病。故此试验对鉴别器质性与功能性心脏病有一定的参考价值。本文的目的,是在心得安试验用药方法上给以改
In recent years, the application of propranolol (beta receptor blocker) to identify structural and functional ECG ST-T changes, frequently reported at home and abroad, this test known as propranolol. Empiric test positive, indicating that patients with increased sympathetic excitability, for the propranolol antagonism, which is more common in cardiac neurosis (including β-receptor hypersensitivity state); propranolol test negative, suggesting that patients with ST-T changes Ann can not be eliminated by the experience, common in coronary heart disease, myocarditis and other organic heart disease. Therefore, the test on the identification of organic and functional heart disease have a certain reference value. The purpose of this article is to reassure empiric test medication
