心电图在肺栓塞严重程度评估中的作用

急性肺栓塞（APE）有较高的发病率和死亡率。因此，对APE患者早期、快速的诊断及危险分层尤为重要。心电图（ECG）反映了APE肺动脉高压引起的一系列病理生理过程，ECG改变与APE患者肺灌注缺损程度、右心室收缩功能、住院期间出现严重并发症有很好的相关性。本文对ECG各种波形改变及DanielECG评分与肺栓塞严重程度之间的相关性进行了综述，旨在增强大家对ECG在肺栓塞危险分层中价值的了解。

Electrocardiogram in evaluating severity of pulmonary embolism

Acute pulmonary embolism （APE） has high morbidity and mortality. So, it is very important for the APE patients to get an appropriate diagnosis and risk stratification as early as possible. Electrocardiogram （ECG） could finely reflect a series of pathological and physiological process caused by APE pulmonary hypertension, and has a good relation with the pulmonary perfusion defect, fight ventricular dysfunction and severe in-hospital complications. In this paper, we review the correlation of various ECG waveforms and Daniel ECG score with the severity of pulmonary embolism. We aim to evaluate the roles of ECG in risk stratification of the pulmonary embolism.
