Acceleration of functional reentry by rapid pacing in anisotropic cardiac monolayers: Formation of multi-wave functional reentries

摘要

Objective: Attempts to cardiovert tachycardia by rapid point pacing can sometimes result in transient or stable increase of the heart rate (acceleration), changed ECG morphology, and/or fibrillation. The goal of this study was to investigate the effect of rapid pacing on the dynamics of functional reentry in monolayer cultures of cardiac cells.
