The initial part of polymorphic ventricular tachycardia as a clue for the sustainability of tachycardia and ablation success: A varying degree of purkinje–Myocardial complicity? Journal of Innovations in Cardiac Rhythm Management, 14(6), 5472-5480. https://dx.doi.org/10.19102/icrm.2023.140662156-39772156-3993https://dx.doi.org/10.19102/icrm.2023.14066https://hdl.handle.net/20.500.12511/11354The cardiac Purkinje system is capable of very rapid burst activity suggestive of its potential role in being a driver of polymorphic ventricular tachycardia (VT) (PMVT) or ventricular fibrillation (VF). It plays a pivotal role, however, not only in the triggering of but also the perpetuation of ventricular arrhythmias. A varying degree of Purkinje–myocardial complicity has been blamed in determining not only the sustained or non-sustained nature of PMVT but also the pleomorphism of the non-sustained runs. The initial part of PMVT before cascading to the whole ventricle to establish disorganized VF can give important clues for ablation of PMVT and VF. We present a case of an electrical storm after acute myocardial infarction that was successfully ablated after identifying Purkinje potentials that triggered polymorphic, monomorphic, and pleiomorphic VTs and VF.enAttribution 4.0 Internationalinfo:eu-repo/semantics/openAccessMultiple ExitsMyocardial SubstratePleomorphic Ventricular TachycardiaPolymorphic Ventricular TachycardiaPurkinjeArticle1465472548010.19102/icrm.2023.140662-s2.0-8516690240537388422Q3
