Analysis of depolarization abnormality and autonomic nerve function after stereotactic body radiation therapy for ventricular tachycardia in a patient with old myocardial infarction

摘要

Electrophysiological findings. A: Chest radiograph with implantable cardioverter-defibrillator insertion and mild cardiac enlargement. B, C: Two types of clinical ventricular tachycardia (VT). D, E: Induced VTs and pace map morphology differed from clinical VTs. F: Multiple VT exits, and pace map site marked in the border zone of the endocardial voltage map. ATP = antitachycardia pacing; DC = direct current; LPO = left posterior oblique view; RAO = right anterior oblique view.
