目的：探讨分析急性心包炎患者的心电图特征及临床意义。方法回顾性分析我：2010年6月~2014年6月查出的46例急性心包炎患者的心电图。结果第1~3d心电图记录29例，ST段抬高25例（86.20%），PR段下移26例（89.65%）；第4~7d心电图记录11例，ST段抬高8例（72.72%），PR段下移6例（63.63%）；第8~14d心电图记录6例，ST段抬高2例（33.33%），PR段下移1例（16.66%）。Ⅰ、Ⅱ、Ⅲ、aVL、aVF、V2-V6导联普遍表现为ST抬高和PR段下移，aVR导联表现为ST段下移和PR段抬高。结论急性心包炎时ST段抬高和PR段下移有较高的敏感性和特异性，有重要诊断价值。“,”Objective Explore the analysis of electrocardiogram (ecg)characteristics and clinical significance in patients with acute pericarditis.Methods Retrospective analysis in June 2010~June 2014 found the 46 cases of electrocardiogram (ecg)in patients with acute pericarditis.Results 1~3 d ecg records 29 cases,ST segment elevation 25 cases (86.20%),PR section down 26 cases (89.65%);4~7 d electrocardiogram record 11 cases,ST segment elevation 8 cases(72.72%),PR section down 6 cases(63.63%);8~14 d electrocardiogram record 6 cases,ST segment elevation in 2 cases(33.33%),PR section down in 1 case(16.66%).Ⅰ,II,Ⅲ,aVL,common symptoms of aVF,V2-V6 lead for ST elevation and PR down,AVR lead performance for ST segment down and PR segment elevation.Conclusion Acute pericarditis with ST segment elevation and PR down has higher sensitivity and specificity,Has important diagnostic value.
