Clinical characteristics associated with bradycardia and asystole in patients with syncope undergoing long-term electrocardiographic monitoring with implantable loop recorder

Background The aim of this retrospective single center cohort study was to assess the occurrence of bradycardia during implantable loop recorder (ILR) monitoring in patients with unexplained syncope and negative conventional testing and to identify clinical predictors of bradycardia and pacemaker implantation.
