目的：探讨尘肺病合并胸膜增厚患者心电图的改变。方法选择85例尘肺病合并胸膜增厚患者作为观察组，另选择身体健康的工人120例作为对照组，分别进行12导联常规心电图检查。结果观察组心电图异常检出率为74．11％，高于对照组的31．67％（ P＜0．01）；观察组异常心电图主要表现分别为心律失常、ST-T改变、肢体导联低电压、心电轴右偏、肺型P波、心脏顺钟向转位等。结论密切观察尘肺病合并胸膜增厚患者的心电图改变，对其心血管疾病的早期诊断、病情评估及治疗具有重要意义。%Objective To investigate the changes of electrocardiogram ( ECG ) of the pneumoconiosis patients with pleural thickening .Methods Eight-five pneumoconiosis patients with pleural thickening were selected as observation group,120 healthy workers were selected as control group ,then the patients in two groups were examined by 12-lead ECG respectively .Results The detection rate of abnormal ECG in the observation group was 74 .11%, which was higher than that(31.67%) in the control group(P<0.01).The abnormal ECG in the observation group was mainly presented as arrhythmia , ST-T segment changes , limb lead low voltage , right electrical axis deviation , pulmonary P wave,cardiac clockwise rotation .Conclusion Closely observation on the changes of ECG of pneumoconiosis patients with pleural thickening is of great significance for the early diagnosis ,severity evaluation and treatment of cardiovascular diseases .
