The Role of Troponin Testing in Patients with Supraventricular Tachycardia, Systematic Review and Meta-Analysis.

Background: Supraventricular tachycardia (SVT) is commonly evaluated in the emergency department (ED). While troponin has been shown to be elevated in SVT, its usefulness for predicting coronary artery disease and future adverse cardiovascular outcomes has not been shown.

Objectives: We aimed to evaluate the prognostic utility of troponin measurement as part of SVT management in the ED.

A clinical approach to an unidentified aerosolized bioterrorism agent: a narrative review for emergency providers.

The current heightened international political climate is accompanied by increased risk of chemical or biological agent weaponization. Historical accounts of biochemical warfare are extensive, and considering the recent use of such agents for targeted attacks, clinicians need to recognize and manage these cases. However, agent properties such as the color, odor, ability to be aerosolized, and long incubation period can introduce difficulties in the diagnostic and management approach.
