Burden and Timing of Premature Atrial Contractions After Electrical Cardioversion of Persistent Atrial Fibrillation Do Not Predict Its Recurrence

摘要

BackgroundThe heart is susceptible to recurrence of atrial fibrillation (AF) during the period immediately following conversion to sinus rhythm (SR). It is less clear whether various onset or trigger mechanisms can predict AF recurrence after direct current (DC) cardioversion of persistent AF.
