如何根据常规心电图的某些提示来预测运动试验结果很有实际意义.近两年来,我们做了183例踏车运动试验,发现ST水平延长者阳性率较高.1 对象与方法1.1 对象 被试者共183例,无器质性病变,胸透、超声心动图检查均无异常,以平静描记的心电图上以R波为主的导联有无ST段水平延长(>0.12秒,并除外过渡型所致者),分为2组.1.1.1 水平延长组(简称延长组)共87例,男:女为2.3:1,年龄40～65岁,平均52.7岁.1.1.2 无水平延长组(简称对照组)共96例,男:女为3.66:1,年龄42～63岁,平均48.27岁.
How to predict the results of exercise test according to some tips of conventional ECG is very meaningful.In the past two years, we made 183 cases of treadmill exercise test and found that ST-level prolongation of the positive rate is higher.1 Subjects and methods 1.1 Subjects were A total of 183 cases, no organic disease, chest X-ray, echocardiography were no abnormality, to tracings of electrocardiogram with R wave-based lead with or without ST segment lengthening (> 0.12 seconds, with the exception of the transition Type), divided into 2 groups.1.1.1 horizontal extension group (referred to as the extension group) a total of 87 cases, male: female 2.3: 1, aged 40 to 65 years, an average of 52.7 years.1.1.2 no horizontal extension Group (referred to as control group) a total of 96 cases, male: female 3.66: 1, aged 42 to 63 years, mean 48.27 years.
