从流行病学看全国肺心病心电图诊断标准

Epidemiol ogical review of national electrocardiographic creteria fur chronic cor pulmonale

为评价我国肺心病心电图诊断标准在流行病学调查中的实用性,对流行病学调查查出的1847例慢性阻塞性肺病患者心电图按我国与世界卫生组织肺心病心电图诊断标准作比较分析.结果按我国标准肺心病的检出率为23.66%;而按世界卫生组织标准确诊和可疑者共8.61%.如将标准定为P_I≥0.25mV和QRS电轴≥+100°为阳性,除V_1呈qR或qr可1项定性,其余指标需2项以上阳性始可诊断,则肺心病检出率为6.06%;而全部指标皆1项阳性即可诊断者为20.19%.认为我国现行肺心病心电图诊断标准可能偏松.

To evaluate epidemiological value of national elecirocar-diographic criteria for chronic cor pulmonale, comparison between national criteria for chronic cor pulmonale and WHO's one was made in 1847- Incidence of chronic cor pulmonale was 23. 66 % in 1847 COPD, patients based on national electrocardiographic criteria , however, according to WHO electrocardiographic criteria, incidence including suspects in cor pulmoanle was 8. 61 %. If any two national indexes including modified P1≥0. 25mV and QRS axis≥ +100? except qR or qr in V1, were adopted in the diagnosis of cor pulmonale. diagnostic rate would be 6. 06%. If diagnosis was made by one single positive index, rate would be 20. 19%. Thus, conclusion could be that made current national elec-trocardographic criteria might not be rigid enough in diagnosis of chronic cor pulmonale.
