Taquicardia supraventricular

Las Vegas F.O.A.M. Blog - 3/18/2015 - By Ketan Patel, MD, FAAEM. 
Director of Clinical Education
"Disclaimer: This blog post is based on a 2015 article chosen for the Lifelong Learning and Self Assessment (LLSA) for Emergency Physicians. This blog post is in no way designed to help facilitate passing of the LLSA exam. Rather, it highlights important literature flagged as relevant to clinical practice and is thus presented here as educational material for training residents. 
Clinical question: What is the best way approach and manage a patient with a tachycardia presenting to the emergency department?
In order to answer this clinical question, this blog post will highlight teachings from the following 2015 LLSA article:
Link MS. Clinical practice. Evaluation and initial treatment of supraventricular tachycardia. N Engl J Med. 2012:367(15):1438-48. 
Article can be downloaded via the following link: 
The first part of this article focuses on characteristics of various atrial tachycardias (along with premature atrial complexes). The latter half of the articles discusses strategies in identifying these tachycardias, differentiating them from ventricular tachycardias and a management algorithm for patient treatment. 
This article has great table, which summarizes the differential diagnosis of supra ventricular tachycardias (SVTs) with rhythm strip examples, causes, regularity, average rates, and response to adenosine. I have summarized some of this data below for completeness, but please reference the article for this information as it a great concise look at SVTs."
