Abstract

This is a PDF file of an article that has undergone enhancements after acceptance, such as the addition of a cover page and metadata, and formatting for readability, but it is not yet the definitive version of record. This version will undergo additional copyediting, typesetting and review before it is published in its final form, but we are providing this version to give early visibility of the article.

Successful ablation of Purkinje ectopy–triggered ventricular fibrillation storm in a patient with orthotopic heart transplantation and severe SARS-CoV-2 pneumonia: a case report

“…The presence of a very early Purkinje potential during PVCs/PMVT and VF may indicate that automaticity or triggered activity from the Purkinje network is the possible mechanism for VF. 8 In this case, successful elimination of VF required careful identification of the very early Purkinje potentials using high-density mapping and an ablation catheter. If challenging cases arise where there is an absence of trigger PVCs and low-voltage areas representing scar or fibrosis, Purkinje de-networking can be considered as an alternative.…”
