Pulseless ventricular tachycardia MRI

Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]; Associate Editor(s)-in-Chief: Aisha Adigun, B.Sc., M.D.[2]

Overview

There are no specific MRI findings associated with pulseless ventricular tachycardia. However, a cardiac MRI may be helpful when structural heart disease is implicated as an etiology and the assessment provided by echocardiography is not satisfactory. A cardiac MRI^[1] is particularly helpful in the evaluation of structural heart disease i.e arrhythmogenic right ventricular cardiomyopathy as well it’s infiltrative diseases such as sarcoidosis.^[2]

Class IIa
“1.In patients presenting with VA who are suspected of having structural heart disease, cardiac magnetic resonance imaging (MRI) or computed tomography (CT) can be useful to detect and characterize underlying structural heart disease. (Level of Evidence B)”
“2. LV imaging can be useful in patients undergoing biventricular pacing. (Level of Evidence C)”
