The clinical symptoms of abnormalities seen during ILR monitoring have not been adequately studied. Aim The aim of this retrospective study was to determine the clinical symptoms which were the best predictors of asystolic or bradycardic responses during ILR monitoring. Methods Patients with either asystole or bradycardia recorded during ILR monitoring were analyzed from our database. The clinical characteristics of these patients were compared to the patients with ILR s who did not have recorded bradycardic episodes. The episodes were characterized as being convulsive or nonconvulsive brief 5 minutes or prolonged 5 minutes and having had a prodrome or no prodrome. Results Eleven patients 4 males and 7 females age 39 11years had asystole or bradycardia on ILR monitoring. Eleven patients 2 males and 9 females age 46 23 had no bradycardiac events. Palpitations convulsive syncope prolonged episode and prodrome were present in 37 vs. 74 P 62 vs. 0 P 87 vs. 0 P 0 and 73 vs. 13 P patients respectively in the asystole bradycardia and non-bradycardia groups. In the asystole bradycardia group
