目的分析艾滋病病毒(HIV)感染者/艾滋病(AIDS)病人(简称HIV/AIDS病人)心电图改变与CD4~+T淋巴细胞(简称CD4细胞)计数的关系,以及HIV/AIDS病人心电图有无特征性改变。方法根据CD4细胞计数结果分级(I级:>500个/μL;Ⅱ级200个/μL至≤500个/μL;Ⅲ级≤200个/μL),比较三组HIV/AIDS病人心电图异常率的差异和各组心电图特征性改变的差异。结果心电图异常率,CD4细胞计数I级为25.0%,Ⅱ级60.5%,Ⅲ级76.7%,三组之间差异有统计学意义(χ~2=16.51,P<0.01)。心电图的特征性改变按频率从高到低依次为快心律失常、ST-T改变、左房室肥大、慢心律失常、低电压、右房室肥大。不同CD4细胞计数组别的异常心电图比较,快心律失常的差异有统计学意义(χ~2=7.01,P<0.05)。结论 HIV/AIDS病人心电图异常率、快心律失常均与CD4细胞计数分级有关。
Objective To analyze the relationship between changes of electrocardiogram (ECG) and counts of CD4 ~ + T lymphocytes (CD4 cells) in patients with HIV / AIDS (HIV / AIDS) and the characteristics of ECG in HIV / AIDS patients change. Methods According to the results of CD4 cell count (level I:> 500 / μL; level Ⅱ 200 / μL to ≤500 / μL; level Ⅲ ≤200 / μL), the abnormality rate of electrocardiogram Differences and differences in the characteristic changes of electrocardiogram in each group. Results The abnormal rate of electrocardiogram was 25.0% for CD4 cell count, 60.5% for grade Ⅱ and 76.7% for grade Ⅲ, there was a significant difference between the three groups (χ ~ 2 = 16.51, P <0.01). Characteristics of ECG changes from high to low in order of fast arrhythmia, ST-T changes, left atrioventricular hypertrophy, arrhythmia, low voltage, right atrioventricular hypertrophy. The differences of ECG in different CD4 cell count groups were statistically significant (χ ~ 2 = 7.01, P <0.05). Conclusion The abnormal rate of ECG and aneurysm in HIV / AIDS patients are related to the CD4 cell count.
