Answer 18

pulmonary embolism

Question 19

when suspecting PE, what parameters should we check in order to rule out myocardial infarction ?

Answer 19

D-dimer levels

ECG

Question 20

what is the first line imaging for stable patient, suspected with PE ?

Answer 20

X-ray (almost always negative)

Answer 25

Well’s criteria
