目的分析临床诊断急性心包炎中,患者心电图的变化特点。方法观察2014年1月~2016年5月我院收治的46例急性心包炎患者(观察组)首次心电图情况。并以同期我院46例急性心肌梗死患者为对照(对照组)。测量各导联ST段和PR段方向和弧度。结果 36例急性心包炎患者呈a VR导联ST段压低,但普遍导联凹陷形ST抬高,a VR导联PR抬高,导联除V1和a VR外PR段出现广泛的下移。患者在发病的第一天检出普遍的PR段改变;发病第二天检出率最高,以后逐渐减低。仅8例心肌梗死患者出现广泛的PR段下移。结论急性心包炎患者心电图区别于急性心肌梗死,会有广泛的PR段下移,有利于急性心包炎的诊断,具有临床推广应用的价值。
Objective To analyze the changes of electrocardiogram in patients with acute pericarditis diagnosed clinically. Methods From January 2014 to May 2016,46 cases of acute pericarditis (observation group) admitted to our hospital for the first time ECG situation. 46 cases of acute myocardial infarction in our hospital as a control (control group). Measure the direction and curvature of the ST and PR segments of each lead. Results In 36 patients with acute pericarditis, ST segment depression in a VR lead was observed. However, ST elevation in the common lead depression, PR elevation in a VR lead, and extensive PR reduction in the leads except V1 and a VR. Patients in the first day of onset detected a common PR segment changes; onset the next day the highest detection rate, and then gradually reduced. Only 8 cases of myocardial infarction patients with extensive PR segment down. Conclusion ECG in patients with acute pericarditis is different from acute myocardial infarction, there will be a wide range of PR segment down, is conducive to the diagnosis of acute pericarditis, with clinical application of the value.
