70例肺栓塞心电图的分析

目的:探讨肺栓塞(PE)及合并冠心病(CAD)患者的心电图(ECG)变化。方法:回顾我院心内科2003年1月至2005年7月确诊为肺栓塞70例患者的ECG变化。患者均经核素肺通气灌注扫描和冠状动脉造影明确诊断。其中50例患者PE合并CAD。结果:70例PE患者ECG异常的发生率为70.0%。其中有助于PE诊断的ECG变化包括:肺型P波、SⅠQⅢTⅢ、完全性右束支传导阻滞(RBBB)以及心前导联T波倒置的总发生率为22.9%。比较单纯PE与PE合并CAD患者ECG异常变化,2组患者ECG异常发生率差异无统计学意义(χ2=2.99,P=0.084)。结论:ECG异常变化对临床PE提供的诊断价值较低。

Electrocardiographic findings in 70 patients with pulmonary embolism

Objective：To assess electrocardiographic changes in patients with pulmonary embolism and some of them complicated with coronary artery disease. Method：To retrospect the electrocardiography （ECG） changes in 70 patients hospitalized in the department of cardiology from Jan. 2003 to July 2005. 50 of them were complicated with CAD. All diagnosis in them were confirmed by ventilation - perfusion scanning and coronary angiography. Result： ECG abnormal rate is 70.0%. The rate of P pulmonale, SI Q T , right bronch block and precardial T wave inversion is 22.9%. Comparing the ECG abnormal rate between PE and PE complicated with CAD patients, there was not statistically significant difference （X^2 = 2.99 P = 0.084）. Conclusion：The ECG alone has very limited value in confirming PE diagnosis.
