Multiple studies have evaluated capnography for the diagnosis of pulmonary embolism; accordingly, we conduct a meta-analysis of these trials. ⋯ Pooled data suggest a potential diagnostic role for capnography when the pulmonary embolism pretest probability is 10% or less, perhaps after a positive D-dimer test result.

We aimed to describe the demographics, care, and outcomes of patients with atrial fibrillation in the emergency department (ED), as well as temporal changes over time. ⋯ The number of ED visits for atrial fibrillation increased markedly during an 8-year period. Although it appears that slightly higher-risk patients are being treated in the province's EDs, fewer patients are being admitted to the hospital, and mortality rates have not increased.
