目的探讨乳糜胸对心电图的影响,并分析其产生的可能机制及临床意义。方法选择80例乳糜胸病例进行心电图分析。选取80例健康体检者作为对照组。按照乳糜胸发生部位不同分3组;按照X线检查判断积液量多少分3组,按抽液前与抽液后分两组,分别对心电图异常发生率进行分析。结果①乳糜胸组发生心电图异常54例(67.5%,54/80);②不同部位的乳糜胸患者中,V4￣V6导联R+S<1.0与右胸V1导联R+S>1.0组比较有统计学意义(p<0.05);③不同积液量的乳糜胸患者窦性心动过速、肢导联低电压的发生率比较,差异有统计学意义(p<0.05);④抽液前后对比组在窦性心动过速、低电压的差异有统计学意义(p<0.05)。结论乳糜胸患者心电图具有心率快,电压低,易改变等特点。
Objective To investigate the effect of chylothorax on electrocardiogram and to analyze its possible mechanism and clinical significance. Methods Eighty cases of chylothorax were selected for ECG analysis. Eighty healthy subjects were selected as control group. In accordance with the different parts of the chylothorax divided into 3 groups; in accordance with the X-ray examination to determine how much the volume of fluid divided into 3 groups, before and after pumping fluid was divided into two groups, respectively, the incidence of abnormal ECG analysis. Results ① There were 54 cases of abnormal electrocardiogram (67.5%, 54/80) in the chylothorax group; ② In the chylothorax patients with different sites, the R + S <1.0 of the V4 ~ V6 lead and the R + S> (P <0.05). ③The incidence of sinus tachycardia and low limb lead voltage in patients with different volume of fluid in the patients with chylothorax showed statistically significant difference (p <0.05) Before and after the contrast group in sinus tachycardia, low voltage difference was statistically significant (p <0.05). Conclusion Patients with chylothorax ECG with heart rate, low voltage, easy to change and so on.
