Abstract

目的探讨急性心包炎心电图PR段的改变并对相关因素分析.方法对78例急性心包炎患者不同时间记录的首次心电图进行分析,测量各导联PR段和ST段改变的方向和幅度,测量心率,并探讨PR段改变与ST段改变以及与心率的关系.以78例早期复极综合征为对照.结果78例急性心包炎患者中,55例(75.1%)在I、Ⅱ、Ⅲ、aVF、V3～V6导联普遍出现PR段下移,aVR导联出现PR段抬高,aVL导联仅3例有PR段改变.上述导联PR段下移幅度为о.05～0.15 mV.第1次记录中69例(87.2%)出现I、Ⅱ、Ⅲ、aVF、V3～V6导联ST段抬高.普遍导联PR段下移伴随ST段抬高的检出率在发病第ld记录的心电图中最高,随后记录的心电图中逐渐降低.PR段的下移与心率无关.在早期复极综合征中仅2.6%记录到PR段下移.结论普遍导联PR段下移伴随ST段抬高是急性心包炎早期心电图的特征性改变.
