目的了解艾滋病患者心电图改变与CD4+T淋巴细胞分级的关系。方法按CD4+T淋巴细胞计数的高低将479例艾滋病患者分为Ⅰ、Ⅱ、Ⅲ级,对各级艾滋病患者的心电图做出诊断。结果三个级别艾滋病患者心电图异常率、左房室肥大率比较,差异均有统计学意义(P<0.05)。其中Ⅱ级与Ⅲ级艾滋病患者心电图异常率比较,差异亦有统计学意义(P<0.05)。三个级别艾滋病患者快心率失常率、慢心律失常率、右房室肥大率、ST-T及T波改变率比较,差异均无统计学意义(P>0.05)。结论Ⅲ级艾滋病患者心电图异常率及快心律失常率高于Ⅰ级与Ⅱ级艾滋病患者,患者心电图改变与CD4+T淋巴细胞分级有关。
Objective To understand the relationship between ECG changes and CD4 + T lymphocyte subsets in AIDS patients. Methods According to the level of CD4 + T lymphocyte count, 479 AIDS patients were divided into Ⅰ, Ⅱ and Ⅲ levels to make a diagnosis of the ECG of AIDS patients at all levels. Results There were statistically significant differences in ECG abnormality rate and left atrial hypertrophy rate between the three levels of AIDS patients (P <0.05). There was also a significant difference in ECG abnormalities between grade Ⅱ and Ⅲ AIDS patients (P <0.05). The rate of gallbladder arrhythmia, right arrhythmia, right ventricular hypertrophy, ST-T and T wave changes in three levels of AIDS patients were not significantly different (P> 0.05). Conclusions The abnormal rate of ECG and the rate of arrhythmia in grade Ⅲ AIDS patients are higher than those in grade Ⅰ and Ⅱ AIDS patients. The changes of electrocardiogram in patients with grade Ⅲ are related to the grade of CD4 + T lymphocytes.
