摘　　要：目的探讨P波最大时限(Pmax),P波离散度(Pd)与房性心律失常的相关性。方法通过12导联心电图同步测定110例房性心律失常的Pmax和Pd,并与对照组比较。结果房性心律失常组的Pmax和Pd明显大于对照组(P<0.01),当Pmax≥110ms,Pd≥40ms时房性心律失常的发生率明显增高。结论体表心电图P波离散度是预测房性心律失常的有效指标,而当Pmax与Pd相结合时预测房性心律失常的特异性和准确性更高。Objective To study the relationship between the maxium time of the P wave(Pmax),P wave dispersion(Pd)and atrial arrhythmia.Methods To survey 12 leads ECG Pmax and Pd of 110 cases with atrial arrhythmia,and compare to the comparative group.Results Pmax and Pd with atrial arrhythmia are higher than comparative group(P<0.01).When Pmax≥110ms,Pd≥40ms,the incidence rates of atrial arrhythmia obviously increased.Conclusion Pd is a reliable index to predict atrial arrhythmia and Pmax+Pd has higher predictive value in significant and accuracy.
