摘　　要：目的探讨P波最大时限(Pmax)与最小时限(Pmin)对阵发性房颤的预测价值。方法回顾性地收集2008年1月至10月行12导联动态心电图监测的心内科住院患者90例,其中阵发性房颤32例,非房颤58例,比较两组的Pmax,Pmin及临床特点。结果阵发性房颤组Pmax较非房颤组明显增大〔(114±15)vs(104±11),P<0.01〕,两组Pmin差异没有统计学意义〔(55±9)vs(58±11)ms,P=0.08〕,24 h平均心率增快〔(89±25)vs(74±15)次/min,P<0.01〕;经校正其他临床因素后显示,Pmax增大及快心室率是心血管病住院患者发生阵发性房颤的独立相关因素。结论 12导联动态心电图Pmax增大及快心室率是预测心血管病住院患者发生阵发性房颤的较好指标。Objective To evaluate the predictive value of the maximum（Pmax） and minimum（Pmin） P-wave durations for paroxysmal atrial fibrillation（PAF）.Methods Ninety consecutive inpatients with heart diseases who underwent 12-lead Holter monitoring during the period of January 2008 to October 2008 were retrospectively collected.There were 32 patients with PAF and 58 with non-atrial fibrillation（NAF）.The Pmax,Pmin and clinical characteristics were compared between the two groups.Results The Pmax and average 24-h heart rate were significantly higher in PAF group than in NAF group（（114±15）vs（104±11） ms,P0.01;（89±25） vs（74±15） beats/min,P0.01）.There was no significant difference in Pmin between PAF and NAF groups.After adjustment for other covariates,it was shown that higher Pmax and average ventricular heart rate were the independent risk factors of PAF in inpatients with heart diseases.Conclusion Higher Pmax and average ventricular heart rate in 12-lead Holter monitoring are reliable predictors for the risk of PAF in inpatients with heart disease.
