Abstract:Objective To discuss electrocardiographic(ECG)changes in acute pulmonary embolism and its clinical significance. Methods ECG characteristics were analyzed before and after treatment in 23 patients with acute pulmnary embolism. Results The parameters such as sinus tachycardia,SⅠQ ⅢT Ⅲor QⅢT Ⅲ, ring bundle branch,ECG showed T to deepen on of precordal leads,terminal R raised up of AVR lead,clock wise rotation,right axis deviation and premature beats improved significantly after treatment(P <0.05). Conclusion Combining with symptoms such as dyspnoea,chest pain and cough,non-specifit ECG changes are of important values in diagnosing acute pulmonary embolism patients.
