Background: Syncope is a very frustrating chief complaint for many in the medical field.  There is no gold standard test and no validated decision instrument. It represents about 3 – 5% of ED visits, 1 – 6% of hospital admissions, and in patients over the age of 65 years it is the 6th most common cause of hospitalization [2][3]. Additionally, both ED and inpatient work ups are notoriously low yield for finding significant pathology. Pulmonary embolism is one of the myriad of diagnoses included in the differential diagnosis of syncope, but there is little information looking at its prevalence amongst hospitalized patients. Fast forward to Oct. 20th, 2016 and there is now some evidence just published in the NEJM: The PESIT Trial.
