Emergency Medicine

Male patient in his early sixties had a recent echocardiogram and was started on an oral anticoagulant. He was brought to resus because someone was worried about PE. Describe the rhythm, what other medication is he likely to be taking (in the context of current rhythm)? His d-dimer test is negative, if it was positive, would you suspect PE in an anticoagulated patient who is not hypoxic, has no chest pain, has no leg swellings, has no history of thromboembolism, and is normotensive?
