Diagnostic potential of non-invasive mapping in the treatment of ventricular tachycardia in a patient with postinfarction scar: a case report

Abstract

A case report of ventricular tachycardia (VT) treatment in a patient after myocardial infarction using non-invasive real-time electrophysiological mapping is presented. This clinical observation demonstrates the diagnostic possibilities of non-invasive mapping in the treatment of VT with hemodynamic instability. Non-invasive mapping can be used as a method for visualizing the early activation and slow conduction zones in hemodynamically instable VT, when effective endocardial mapping is not possible.
