阵发性心房颤动患者P波离散度临床研究

Clinical study on P _ wave dispersion in patients with PAF

目的探讨阵发性心房颤动患者P波离散度的变化。方法观察40例阵发性心房颤动患者P波离散度 ,并与无阵发性心房颤动的患者比较。结果心房颤动组P波离散度增高 (48.05±8.38ms) ,与对照组(36.44±4.84ms)差异有非常显著性意义 (P<0.01) ;P波离散度为40ms时 ,预测心房颤动的敏感性为82 % ,特异性为85% ,阳性预测准确度为83.33 %。

Objective Analyse P _ wave dispersion in patients with PAF.Methods Measuring P _ wave dispersion from 12_ lead surface electrocardiogram of 40 patients with a history of PAF and 30 no _ PAF control subjects.Results P _ wave dispersion was significantly higher in patients(48.05±8.38 ms) than in control subjects(36.44±4.84 ms)(P<0.01),P _ wave dispersion value of 40 ms separated patients from control subjects with a sensitivity of 82% and a specificity of 85%.Conclusion P _ wave dispersion was an electrocardiographic marker that could be used for prediction of PAF.
