我们在对肺心病心电图的观察中,注意到 P 波倾斜角(下称β角)的大小在反映肺心病右房容积和压力变化方面,有较好的敏感性和特异性,现报道如下。临床资料一、一般资料(一)正常组:临床上无咳、痰、喘病史;胸部透视或胸片正常者共120例作为对照组。(二)慢性支气管炎(慢支)-肺气肿组:体征及 X 线检查符合慢支诊断标准者120例,其中58例合并
In our observation of electrocardiogram of pulmonary heart disease, we noted that the magnitude of the P wave tilt angle (beta angle) has good sensitivity and specificity in reflecting the right atrial volume and pressure changes of pulmonary heart disease and is reported as follows. Clinical data First, the general information (a) normal group: no clinical cough, sputum, asthma history; chest X-ray or normal chest film a total of 120 cases as a control group. (B) chronic bronchitis (chronic bronchitis) - emphysema group: signs and X-ray examination consistent with the criteria for the diagnosis of chronic bronchial 120 cases, of which 58 cases of merger
