Entrainment of ventricular tachycardia with V‐shaped diastolic activation pattern: Is the pacing site in or out?

Description
Summary:The use and interpretation of entrainment mapping, or continuous resetting, of a reentrant ventricular tachycardia, has been regarded as the gold standard for delineation of the components of a reentrant circuit. However, there are both inherent limitations and interpretative pitfalls to entrainment mapping. Beyond the far-field (FF) signals, the multiple near-field (NF) components may also be recorded at a given site and pacing typically interacts and captures only one component of the local activation. In the evaluation of the entrainment response, it is crucial to distinguish the NF electrogram captured from FF or other NF components to accurately measure the post-pacing interval, particularly in the presence of multiple NF signals This article is protected by copyright.
