观察肺气肿、肺心病病人深吸气后QRS向量环的改变情况,有助于肺心病的早期诊断。我们进行了如下研究: 材料和方法:对照组:正常人35例,均系本院职工,经体检心、肺、肝、肾无异常发现,其中男13人,女22人,年龄17～54岁。二、肺气肿、肺心病(符合1977年全国第二次肺心病专业会议制订的诊断标准)病人50例,均系门诊病人,男36人,女14人、年龄28～74岁。两组均作了平静呼吸及深吸气后心电向量图检查,纪录QRS向量环的改变。
Observed emphysema, pulmonary heart disease patients after deep inspiration QRS vector ring changes, contribute to the early diagnosis of pulmonary heart disease. We conducted the following studies: Materials and Methods: Control group: normal 35 cases, all of our hospital staff, physical examination heart, lung, liver and kidney were found no abnormalities, including 13 males and 22 females, aged from 17 to 54 year old. Second, emphysema, pulmonary heart disease (in line with the 1977 National Conference on the diagnosis of pulmonary heart disease professional standards) 50 patients were outpatients, 36 males and 14 females, aged 28 to 74 years. Both groups were made to calm breathing and deep inspiration after ECG vector chart to record the change of QRS vector ring.
