心电图在急性肺栓塞诊断的效果分析

目的观察分析心电图在急性肺栓塞中的诊断结果,总结其临床诊断价值。方法选取2008年12月至2010年12月32例急性肺栓塞的患者,观察分析首次住院时、溶栓后、出院前的心电图变化,进行统计学分析。结果 32例患者在入院时以TⅢ倒置发生率最高,其次为SI>0.1mV的发生率,明显高于其它心电波形的倒置发生率(P<0.05),具有统计学意义;溶栓后以TⅢ倒置明显变浅或直立、QⅢ明显减少或消失、QRS波群的电轴向左移、SI变浅为主要的心电图改变;出院时QⅢ明显减小,RⅢ明显减小,RⅡ明显增大。结论对于临床症状及心电图改变,疑似急性肺栓塞的患者,应结合实际病情作进一步检查,尽早诊断,及时制定出抗凝、溶栓等治疗方案,心电图在急性肺栓塞中具有重要的临床诊断价值。

Objective To observe the analysis of ECG in the diagnosis of acute pulmonary embolism,concluded its diagnostic value.Methods Our hospital from December 2008 to December 2010 32 cases of acute pulmonary embolism in patients,observed and analyzed for the first time in hospital,after thrombolysis,pre-hospital ECG changes,for statistical analysis.Results 32 patients on admission to the highest incidence of TⅢ inversion,followed by SI 0.1mV incidence was significantly higher than other ECG waveform inversion rate（P0.05）,with statistical significance;thrombolysis to TⅢ significantly lighter upside down or upright,QⅢ significantly reduced or disappeared,QRS left axial electric wave group,SI shallow as the main electrocardiographic changes;discharge QⅢ significantly reduced,RⅢ significantly reduced,RⅡ significantly increased.Conclusion For the clinical symptoms and ECG changes in patients with suspected acute pulmonary embolism,should be combined with the actual condition for further examination,early diagnosis,timely development of anticoagulant,thrombolytic and other treatment options,electrocardiogram in acute pulmonary embolism in diagnosis has important clinical value.
