Elective cardioversion is a common and effective therapy for many atrial arrhythmias, however the procedure is not without risk. One risk from cardioversion is the R-on-T phenomenon. This article provides an overview of anatomy and physiology relating to R-on-T, a case of R-on-T following elective cardioversion for atrial fibrillation and important considerations for elective cardioversion in the emergency department environment.
