摘要
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 ,5 5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 0 0 5~ 0 15mV。第 1次记录中 6 9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 1d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。
Objective The aim of this study is to investigate the PR segment changes and analyze the correlative factors in patents with acute pericarditis.Methods The electrocardiograms of 78 patients with acute pericarditis were analyzed according to the time of onset of the disease.The changes of orientation and amplitude of PR segment and ST segment in each lead were surveied and heart rate was measured.The relation between PR segment alteration and the changes of ST segment or heart rate were also studied.Seventy eight patients with early repolarization syndrome were assigned as control group.Results Of 78 patients with acute pericarditis,55(75 1%) had PR segment depression in leads Ⅰ,Ⅱ,Ⅲ,aVF,V 3~V 6,which coincided with PR segment elevation in lead aVR.Only 3 patients showed PR segment deviation in lead aVL.The deviation of PR segment in these leads was 0 05 0 15 mV.The ST segment elevation was recorded in 68 patients(87 2%) in the first day.The incidence of generalized PR segment depression accompanied by generalized ST segment elevation was the highest in the first recording day, then was gradually decreased in the subsequent recording days.There was no relationship between PR segment deviation and heart rate.Only 2 6% of patients with early repolarization syndrome had generalized PR segment depression.Conclusion Generalized PR segment depression complicated with ST segment elevation in the same lead is an early characteristic change of electrocardiogram in acute pericarditis.
