摘　　要：目的研究心电图P波离散度(Pd)与P波最大时限(Pmax)的平行和系列试验诊断对阵发性心房颤动(PAF)的预测意义。方法以2022年1月至2023年11月来宾市人民医院收治的60例PAF患者为研究组,以同期医院收治的60例无心房颤动患者为对照组。对比两组心电图指标及诊断效能。结果研究组心电图指标中P_(max)、Pd均高于对照组,P_(min)低于对照组,P<0.05;两组PR间期对比,P>0.05。以12导联同步心电图机检查结果为金标准,Pd≥40 ms、系列试验敏感性低于平行试验,系列试验敏感性低于P_(max)≥110 ms,Pd≥40 ms、系列试验的特异性、阳性预测值与符合率均高于平行试验,系列试验的特异性、阳性预测值与符合率均高于P_(max)≥110 ms,P<0.05。结论PAF的初级预测筛查可采用敏感性较高的平行试验,在此基础上二次筛查可采用特异性较高的系列试验,两种方式结合能够对PAF的发生进行早期准确预测。Objective:Tostudy the predictive significance of parallel and series tests of P wave dispersion(Pd)and P wave maximum time limit(Pmax)on paroxysmal atrial fibrillation.Methods:From January 2022 to November 2023,60 patients with PAF in Laibin People's Hospital were taken as the study group,and 60 patients without atrial fibrillation in the same period were taken as the control group.The ECG indexes and diagnosis of the two groups were compared.Results:The ECG indexes of the study group were higher than those of the control group,and the Pmax was lower than that of the control group,P<0.05.Comparison of PR interval between the two groups,P>0.05.Taking the results of 12-lead synchronous electrocardiograph as the gold standard,the sensitivity of series tests is lower than that of parallel tests,and the sensitivity of series tests is lower than that of Pmax≥110 ms,and the specificity、positive predictive value and coincidence rate of series tests are higher than that of parallel tests,and the specificity、positive predictive value and coincidence rate of series tests are higher than that of Pmax≥110 ms,P<50.05.Conclusion:The primary predictive screening of PAF can adopt parallel tests with high sensitivity,and on this basis,the secondary screening can adopt a series of tests with high specificity.The combination of the two methods can accurately predict the occurrence of PAF at an early stage.
