Abstract
Diagnosing and treating supraventricular tachycardias is routine in emergency medicine, and new strategies can improve efficiency and outcomes. This review provides an overview of supraventricular tachycardias, their pathophysiology, differential diagnosis, and electrocardiographic features. Clinical evidence guiding contemporary practice is determined largely by multiple observational studies, with few randomized controlled trials. Current prehospital and emergency department management strategies beyond the use of adenosine and calcium channel blockers are addressed. Diagnostic and therapeutic recommendations are provided, based on the best available evidence.
