本文测量了90例临床已确诊为慢性肺源性心脏病患者的IPIV_1数值,并与100例慢性支气管炎合并肺气肿患者的心电图和100例正常人心电图以及现有诊断标准进行了对比,以探讨IPI_(v1)对肺心病的诊断价值。IPI_(v1)以≥0.03毫米·秒为诊断指标,提示右心房异常。肺性P波和IPI_(v1)间有密切关系,两者可互相补充以提高肺心病的诊断符合率。
In this paper, we measured the IPIV_1 values of 90 patients with clinically diagnosed chronic cor pulmonale and compared them with those of 100 patients with chronic bronchitis and emphysema, as well as the existing diagnostic criteria To investigate the diagnostic value of IPI_ (v1) on pulmonary heart disease. IPI_ (v1) ≥ 0.03 mm · s as a diagnostic indicator, suggesting right atrial abnormalities. Pulmonary P wave and IPI_ (v1) are closely related between the two can complement each other to improve the diagnostic accuracy of pulmonary heart disease.
