<prompt> All of the following are true of pulmonary embolism except:Sudden onset of pleuritic pain and hemoptysis and hypotension.ECG shows evidence of acute left ventricular stress.Pulmonary angiography is gold standardCTPA is imaging modality of choice  <response>: Classic Findings in Pulmonary Embolism:- Right Hea strain and Acute Cor Pulmonale - sudden onset of pleuritic chest pain, hemoptysis and hypotension - Tall, peaked P waves in lead II P pulmonale - Right axis detion - Right bundle-branch block - S1Q3T3 pattern. On Xray :- Hamptons hump, Westermark sign areas of relative oligemia secondary to decreased caliber of regional pulmonary aeries and Pallas sign Enlarged right descending pulmonary aery are seen. - CTPA is imaging modality of choice - It shows Rt. ventricular stress instead of left ventricular stress.
