摘　　要：目的探讨心电图P-R间期延长临床应用新认识,旨在为提高飞行人员P-R间期延长的鉴别诊断提供参考依据。方法结合飞行人员心电图检查资料及近年来相关文献报道,对P-R间期延长临床应用新认识进行综述。结果 1P-R间期延长伴窄QRS波群:以一度房室阻滞最为常见,此外,尚可见于房室结慢径路传导、迷走神经张力过高、干扰性P-R间期延长,也可能是双束支同步传导延缓等。2P-R间期延长伴宽QRS波群:多见于双束支不同步阻滞,亦可为一度房室阻滞合并一侧束支三度阻滞等。3P-R间期显著延长(>0.35 s)要考虑P-R间期过度延长综合征可能。结论 P-R间期延长除常见于一度房室阻滞外,还可揭示多种心电现象,具有重要的临床应用价值。Objective T o study the new clinical application of P-R interval prolongation of electrocardiogram so as to provide reference for increasing differential diagnosis of P-R interval prolongation am ong flight personnel.Methods E lectrocardiogram data of the flight per-sonnel and pertinent literature reports in recent years w ere com bined to sum m arize new clinical application of P-R interval prolongation .Re-sults ①P-R interval prolongation w ith narrow QRS wavegroup:m ost com m on w ith I atrial-ventricular block, and occasionally w ith atri-oventricular node slow pathw ay conduction,high vagal tone,interfering P-R interval prolongation,and double bundle branch synchronized conduction delay.②P-R interval prolongation w ith w ide QRS wave group:com m only seen in double bundle branch out-of-sync block,and I atrial-ventricular block com bined w ith one-side bundle branch III atrial-ventricular block .③R em arkable P-R interval prolongation (>0 .35 s) m ight be related to P-R interval excessive prolongation syndrom e.Conclusion B esides I atrial-ventricular block,P-R interval prolongation can reveal various electrocardio phenom ena,w hich has significant clinical application values.
