摘要
目的探讨P波最大时限(Pmax)和P波离散度(Pd)对高血压合并阵发性心房颤动(PAF)患者的预测价值。方法采用12导联同步心电图记录方法测定82例高血压合并阵发性心房颤动(PAF)患者(观察组)的Pmax、P波最短时限(Pmin)和Pd,同时与66例原发性高血压不合并PAF的患者(对照组)进行比较,分析上述指标对高血压合并PAF发作预测的敏感度、特异度和阳性预测值。结果观察组Pmax和Pd分别为(120.5±10.0)ms和(47.6±9.0)ms,均显著高于对照组[(101.5±6.5)ms和(28.5±7.5)ms],组间比较差异有统计学意义(P<0.05);Pmax预测PAF的敏感度为84.5%,特异度为72.0%,阳性预测值为82.4%;Pd预测PAF的敏感度为78.0%,特异度为80.0%,阳性预测值为86.1%;两者联合应用的敏感度为79.3%,特异度为89.0%,阳性预测值为91.7%。结论 Pmax和Pd是预测高血压合并PAF的两个简便可靠的心电图指标,两者联合应用可提高预测的特异性和阳性预测值。
Objective To investigate the predictive value of maximum P wave duration（Pmax） and P wave dispersion（Pd） in hypertensive patients combined with paroxysmal atrial fibrillation（PAF）.Methods 12-lead simultaneous ECG was used to measure the Pmax,Pmin and Pd in 82 cases of hypertension patients combined with PAF（observation group）.The results were compared with 66 cases of hypertensive patients who were not combined with PAF（control group）.Then the sensitivity,specificity and positive predictive value of these indicators to hypertension combined with PAF prediction were analyzed.Results Pmax and Pd in the observation group were（120.5±10.0） ms and（47.6±9.0） ms respectively,which were significantly higher than those of the control group [（101.5±6.5）,（28.5±7.5） ms],the differences between the two groups were statistically significant（P 0.05）.The sensitivity,specificity and positive predictive value of Pmax to PAF prediction were 84.5%,72.0% and 82.4%;which of Pd to PAF prediction were 78.0%,80.0% and 86.1%;the sensitivity,specificity and positive predictive value of their combination were 79.3%,89.0% and 91.7%.Conclusion Pmax and Pd are two simple and reliable ECG indicators to predict PAF,combined application of both of them can improve the prediction specificity and positive predictive value.
