Abnormal Response of Superior Sinoatrial Node to Sympathetic Stimulation Is a Characteristic Finding in Patients With Atrial Fibrillation and Symptomatic Bradycardia Running title: Joung et al.; Superior Sinoatrial Node Dysfunction in AF

Abstract

Background We hypothesize that unresponsiveness of superior sinoatrial node (SAN) to sympathetic stimulation is strongly associated with the development of symptomatic bradycardia in patients with atrial fibrillation (AF). Methods and Results We performed 3-dimensional endocardial mapping in healthy control (Group 1, n=10) and in patients with AF without… (More)
