摘要
目的 探讨体表12导联心电图P波离散度(Pd)和P波最大时限(Pmax)对房性心律失常的预测价值.方法 选取2013年10月~2015年4月嘉善县第一人民医院收治的频发房性早搏、短阵房速患者51例计为房性心律失常组,通过12导联心电图同步检查测定P波离散度(Pd)和P波最大时限(Pmax),并与健康体检者53名(对照组)进行对比.结果 房性心律失常组的Pd和Pmax均明显大于对照组,Pd≥40ms预测房性心律失常的敏感度、特异度及诊断符合率较Pmax≥100ms高,Pd≥40ms联合Pmax≥100ms诊断时,敏感度上升,而特异度和诊断符合率下降.结论 体表心电图Pd是预测房性心律失常的有效指标,Pd和Pmax联合检测能提高诊断敏感度.
Abstract
Objective To explore the predictive value of P wave dispersion (Pd) and maximum P wave duration (Pmax) of 12 lead ECG in patients with atrial arrhythmia.Methods51 cases of atrial arrhythmia group from October 2013 to April 2015 in Jiashan County First People's Hospital, patients with frequent atrial premature atrial tachycardia, were examined for the determination of P wave dispersion by 12 lead electrocardiograms (Pd) and maximum P wave duration (Pmax), and 53 healthy persons (control group) were compared.ResultsAtrial arrhythmia group Pd and Pmax were significantly higher than the control group, the rate is Pmax=100ms with Pd=40ms high prediction of atrial arrhythmia sensitivity, specificity and diagnostic, Pd=40ms=100ms combined with Pmax diagnosis, the sensitivity increased, but the specificity and diagnostic rate of decline.ConclusionPd is an effective index to predict atrial arrhythmias, and the combined detection of Pd and Pmax can improve the diagnostic sensitivity.
