Identity the true statement about Pulmonary embolism:
S1 Q3 T3 is the most common ECG finding seen
There will be Left axis deviation
D-dimer is the gold standard investigation
Sinus tachycardia is most common finding on ECG
S1 Q3 T3 is highly predictive sign but not the most common ECG finding. And there will be right axis deviation.
D-Dimer is best for screening not gold standard investigation.
