Key result
Non-invasive electrocardiographic imaging accurately localized the origin of ventricular tachycardia to the endocardial surface of the right ventricular outflow tract, confirmed by invasive mapping.
Why the study?
Does non-invasive electrocardiographic imaging accurately diagnose and localize ventricular tachycardia with ventriculoatrial retrograde conduction in a patient with wide QRS complex tachycardia?
Case Report (n=1)
No
Does non-invasive electrocardiographic imaging accurately diagnose and localize ventricular tachycardia with ventriculoatrial retrograde conduction in a patient with wide QRS complex tachycardia?
Non-invasive electrocardiographic imaging can accurately localize the endocardial origin of ventricular tachycardia and differentiate it from supraventricular tachycardia with aberrant conduction, effectively guiding successful catheter ablation.
Non-invasive ECGI feasible in one RVOT VT case; leaves open validation before clinical use.
A case report of differential and topical diagnosis of ventricular tachycardia from right ventricular outflow tract endocardial surface with ventriculoatrial retrograde conduction using non-invasive electrocardiographic imaging is presented.

Chmelevsky et al. (2020) conducted a case report in Ventricular tachycardia with ventriculoatrial retrograde conduction (n=1). Non-invasive electrocardiographic imaging (ECGI) was evaluated on Topical and differential diagnosis of wide QRS complex tachycardia. Non-invasive electrocardiographic imaging accurately localized the origin of ventricular tachycardia to the endocardial surface of the right ventricular outflow tract, confirmed by invasive mapping.
