Case report demonstrates successful ablation of Purkinje-related ventricular tachycardia after myocardial infarction, highlighting preservation of fascicular conduction.
Idiopathic left ventricular tachycardia (ILVT) is commonly recognized as a Purkinje-related reentrant ventricular tachycardia (VT) in patients without underlying heart disease, 1 but it has also been reported to manifest subsequent to myocardial infarction (MI).2 In this report, we present two forms of narrow QRS VT that emerged during the chronic phase of MI. These tachycardias were diagnosed as reentrant tachycardia involving the injured Purkinje network and treated with ablation without damaging the fascicular conduction system.
