The Impact of the Spatial Distribution of Ventricular Extrasystoles on Implantable Cardioverter-Defibrillator Recipients.

ABSTRACT:

Introduction

Premature ventricular complexes (PVC) are a common phenomenon observed in both normal and pathological heart conditions. However, they do not always behave in the same way. Different PVCs present with varying QRS morphologies, mechanisms, and origin sites. These differences may imply distinct prognoses. To date, the impact of the three-dimensional distribution of PVCs across the heart on the prognosis of ICD recipients has not been adequately investigated.

Material and methods

We conducted an ambidirectional cohort study. Patients underwent two twelve-lead ambulatory ECG recordings during follow-up. The spatial distribution of PVCs was analyzed using the algorithm proposed by Kuchar et al. The impact of this spatial distribution on clinical variables was assesse
