Wide complex tachycardia risk factors
Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]
Overview
Risk factors for the ventricular tachycardia as a cause of wide complex tachycardia include a history of prior myocardial infarction, a history of congestive heart failure, and a history of recent angina pectoris. These three historical features have positive predictive values for VT of > 95% in a small study, but sensitivities of 66%, 24%, and 24%, respectively.[1] Wide complex tachycardia will be due to VT in 98% of cases if there’s a history of structural heart disease. Only 7% of patients with SVT with aberrancy will have had a prior myocardial infarction (MI).
