From 小麻, in those of research they distribute pleural effusion into two topics; Transudates and Exudates. Roughly separate this two categories; transudates = congestive heart failure, exudates = infection. There is a great description about them in 小麻. When we talk about pleural effusion, we should know about the Light's criteria and exudative criteria. Last but not least, same as @JYC replyed 請愛用小麻.
我覺得合計出版社的實用心電圖判讀指南寫得很不錯，可以參考看看！然後可以上https://lifeinthefastlane.com/有很多實例可以學習，學習到基本判讀後，最重要的是懂得如何實際運用，多看多自己判讀才是重點，這也是最困難的地方，不然背出一推Criteria也沒什麼用，上網多看看Mattu's Emergency ECG Case of the Week的影片，讓Amal Mattu大師教你如何融會貫通！
