如何根据常见心电图的某些提示来预测运动试验阳性是很有意义的。我们发现ST段水平延长是预测运动试验阳性的参考指标,现将我们所见报道如下。材料和方法被试者232例经体检无器质性病变,X线胸透、超声心动图均正常。描记平静心电图,观察以R波为主导联上ST段有无水平延长>0.12s,除外正常过渡型所致者。 1.水平延长组(简称延长组):共116例,男:女=1.36:1,年龄38—65岁,平均52.6岁。
How to predict the positive of exercise test based on some common ECG tips is of great significance. We found that prolongation of the ST segment is a good predictor of positive test motility, as we report below. Materials and Methods The subjects were 232 cases of non-organic disease by physical examination, X-ray thoracentesis, echocardiography were normal. Tranquill transthoracic electrocardiogram, to observe the R-wave-based ST-segment extension with or without horizontal extension> 0.12s, except for those caused by normal transitional type. 1. Horizontal extension group (referred to as extension group): a total of 116 cases, male: female = 1.36: 1, aged 38-65 years, mean 52.6 years old.
