近年来,随着社会的发展,人们的工作及生活压力日益加重,植物神经功能不平衡的病人日益增多,多见于青、中年女性。由于不平衡的植物神经系统对心血管的调节作用,这些病人出现窦性心动过速、心悸、气短、多汗、失眠等表现。心电图上可呈现T波低平或轻度倒置、ST段延长或水平压低,在Ⅱ、Ⅲ、aVF导联往往更为明显。这些病人一般无器质性心脏损害,而心电图ST-T的变化往往可能使临床医生的诊断出现失误。这就需要鉴别心电图ST-T异常是由心脏器质性改变或功能性改变引起。而心得安试验是临床常用的鉴别方法之一。我院对106例心电图ST-T改变的患者,进行了心得安试验,比较用药前后的心电图变化报告如下:
In recent years, with the development of society, people’s work and life pressure is aggravating day by day. Patients with unbalanced function of autonomic nerves are more and more common in young and middle-aged women. Due to unbalanced autonomic nervous system cardiovascular regulation, these patients appear sinus tachycardia, palpitations, shortness of breath, hyperhidrosis, insomnia and so on. Electrocardiogram may show T wave low or mild inversion, ST segment extension or horizontal depression, in Ⅱ, Ⅲ, aVF lead is often more obvious. These patients generally have no organic heart damage, and ECG ST-T changes may often make the clinician’s diagnosis error. This requires that the ECG ST-T abnormalities be identified as either due to organic or cardiac changes in the heart. The trial of anxiety is one of the common clinical identification methods. Our hospital on 106 cases of ECG ST-T changes in patients with propranolol, compare the ECG changes before and after the report as follows:
