Abstract

The optimal duration of monitoring of patients with recurrent unexplained syncope who undergo prolonged monitoring with an implantable loop recorder is unknown. We examined the probability of syncope in a group of 167 patients with this condition who underwent prolonged monitoring with an implantable loop recorder. A 12-month monitoring period appears to capture >90% of episodes. Syncope is most likely to occur in younger patients with less heart disease and more frequent syncope. There is a low risk of syncope after 1 year of monitoring without an event.
