《急诊每日一题》肺梗塞时心电图表现2021年1月

Question 问题：

Pulmonary embolism can have ECG findings suggestive of acute RV strain, such as deep T-wave inversions in leads V1, V2 and V3, RBBB, or S1Q3T3. PE can also present with ST-segment elevation mimicking anterior wall MI. What is the mechanism? 

肺梗塞会有提示急性右室劳损，如V1，V2，V3导联深度T波倒置，或右束支传导阻滞，或S1Q3T3。肺梗塞还会出现类似于前壁心梗的ST抬高。其机制是什么？

Answer 答案：

This is likely due to acute RV strain and poor left ventricular filling resulting in decreased blood flow to the coronaries. 

这很可能是由于急性右室劳损和左心室充盈不良导致冠状动脉血流下降。
