心电图在确定缺血性心脏病的诊断中具有重要意义。ST段水平型压低和T波倒置被认为是冠心病的特征;然而对于非特异性ST-T改变(T波平坦或轻微倒置,ST段轻度、非水平型压低)的解释仍有疑问。最近Furberg介绍一种新方法,通过给予心得安以评价非特异性心电图改变。本文报导了用此法研究143例的结果,其中41例为确诊的心脏病患者(31例冠心病,10例左心肥厚和劳损)作为对照组。其余102例具有非特异性ST—T改变的患者根据其临床病史分成两组:第1组53例,无主诉或诉述显然非心绞痛性胸痛;第2组49例,胸痛虽不典型,但不能排除心绞痛。方法:在作了休息时的基础心电图后,患者口服
ECG in the diagnosis of ischemic heart disease is of great significance. ST-segment horizontal depression and T-wave inversion are considered to be characteristic of coronary heart disease; however, there is doubt as to the interpretation of nonspecific ST-T changes (flat or slightly inverted T waves, mild ST depression, and non-horizontal depression). Furberg recently introduced a new method to assess non-specific ECG changes by giving prophylaxis. This article reports the results of 143 studies using this method, of which 41 were diagnosed with heart disease (31 with coronary heart disease, 10 with left ventricular hypertrophy and strain) as a control group. The remaining 102 patients with nonspecific ST-T changes were divided into two groups according to their clinical history: Group 1 53 patients, no complaints or complaints apparently non-angina chest pain; Group 2 49 patients, although not typical of chest pain, but can not rule out Angina. Method: After taking the rest of the basic electrocardiogram, the patient was taken orally
