摘要 目的 探讨体表心电图P波离散度(Pwd)的变化预测阵发性心房颤动(PAF)的临床价值.方法 观察85例PAF患者(观察组)和85例健康人(对照组)的同步12导联心电图,记录两组最大P波时限(Pmax)、最小P波时限(Pmin)及P波离散度(Pwd).同时进行超声心动图检测,记录两组左房内径(LAD)和左室射血分数(LVEF).结果 Pmax两组分别为(131.2±7.2)t/ms和(94.0±6.2)t/ms,Pwd两组分别为(53.3±7.4)t/ms和(25.7±7.8)t/ms,差异均具有统计学意义(均P<0.05).最大P波间期与左LAD和LVEF呈正相关(P<0.05).结论 Pwd、Pmax和LAD是交叉预测PAF的有效指标之一.
