SYNCOPE: PACING VERSUS RECORDING IN THE LATER YEARS. A RANDOMIZED PRAGMATIC CLINICAL TRIAL OF STRATEGIES OF PERMANENT PACEMAKER VERSUS IMPLANTABLE CARDIAC MONITOR IN OLDER PATIENTS WITH SYNCOPE

摘要

BACKGROUND: Syncope with bifascicular block may be caused by intermittent complete heart block, but competing diagnoses may co-exist. We tested the hypothesis that in patients with syncope and bifascicular heart block a strategy of empiric permanent pacing (PM) reduces major adverse events more effectively than acting on the results of an implantable cardiac monitor (ICM).
