Case study: analysis of dual chamber rate responsive pacing in atrial fibrillation.
This article presents a case study of a patient who required a dual chamber rate responsive pacemaker to assist in managing atrial fibrillation. The patient developed significant bradycardia when treated with the dose of propafenone required to convert atrial fibrillation, so the pacemaker was inserted. An example of a paced rhythm is presented and a differential diagnosis approach is used to discuss the possible interpretations of the rhythm. A brief explanation of the actual cause of the observed paced rhythm is presented.
