摘　　要：目的:探讨P波离散度(Pd)能否预测糖尿病患者伴发的阵发性心房颤动的发生。方法:观察42例有阵发性心房颤动病史的糖尿病患者(A组)的最大P波时限(Pmax)、最小P波时限(Pmin)、P波离散度(Pd)及左房内径(LAD),并与43例无阵发性心房颤动病史的糖尿病患者(B组)比较。结果:A组的Pmax及Pd显著高于B组;Pmin、LAD差异无显著。Pmax>110 ms或Pd>40 ms时,预测心房颤动的敏感性较高;Pmax>110ms+Pd>40ms时,预测心房颤动的特异性明显增高。结论:Pd增高可预测糖尿病患者伴发的阵发性心房颤动的发生,Pmax>110ms+Pd>40ms联用时可提高预测心房颤动的特异性、阳性预测值。Objective: To investigate whether P wave dispersion (Pd) is a predicting index for the occurrence of paroxysmal atrial fibrillation (PAF) in patients with diabetes. Methods: The maximum P wave duration (Pmax), the minimum P wave duration (Pmin), Pd and left atrial dimension (LAD) were measured in 42 diabetics with PAF history (group A) and 43 without PAF history (group B). Results: Only Pmax and Pd were significantly higher in group A than in group B. For predicting the occurrence of PAF, the higher sensitivity was achieved by only use of Pmax >110ms or Pd >40ms, and the higher specificity by use of them. Conclusion: The increase of Pd can predict the occurrence of PAF in diabetics. The combined use of Pmax >110 ms and Pd >40 ms is able to improve the sensitivity and specificity of PAF prediction.
