Macroreentry as a Mechanism of Atrial-Induced Ventricular Ectopic Beats: A Laboratory Curiosity?

During electrophysiologic study in a patient, programmed stimulation of the atrium induced fixed coupled ventricularpremature beats on the basis of infra ventricular macroreentry.

Description
Summary:During electrophysiologic study in a patient, programmed stimulation of the atrium induced fixed coupled ventricularpremature beats on the basis of infra ventricular macroreentry. This type of macroreentry, which was reproducible, appears to have been merely a “laboratory curiosity” and never played a clinical role in this patient with chronic recurrent ventricular tachycardia.
