Randomized assessment of syncope trial.
To the Editor: The recent article published in Circulation by Krahn et al1 underlines the usefulness of implantable loop recorders in the investigation of unexplained syncope. Patients with unexplained syncope were randomized to a “conventional” investigation strategy or to a “prolonged monitoring” strategy with an implantable loop recorder, with the latter strategy yielding a higher diagnostic...
متن کاملCost implications of testing strategy in patients with syncope: randomized assessment of syncope trial.
OBJECTIVES We sought to assess the cost implications of two investigation strategies in patients with unexplained syncope. BACKGROUND Establishing a diagnosis in patients with unexplained syncope is complicated by infrequent and unpredictable events. The cost-effectiveness of immediate, prolonged monitoring as an alternative to conventional diagnostic strategies has not been studied. METHOD...

متن کاملRandomized assessment of syncope trial: conventional diagnostic testing versus a prolonged monitoring strategy.
BACKGROUND Establishing a diagnosis in patients with unexplained syncope is complicated by infrequent and unpredictable events. Prolonged monitoring may be an alternative strategy to conventional testing with short-term monitoring and provocative tilt and electrophysiological testing. METHODS AND RESULTS Sixty patients (aged 66+/-14 years, 33 male) with unexplained syncope were randomized to ...
متن کاملPrevention of Syncope Trial (POST): a randomized, placebo-controlled study of metoprolol in the prevention of vasovagal syncope.
BACKGROUND Previous studies that assessed the effects of beta-blockers in preventing vasovagal syncope provided mixed results. Our goal was to determine whether treatment with metoprolol reduces the risk of syncope in patients with vasovagal syncope. METHODS AND RESULTS The multicenter Prevention of Syncope Trial (POST) was a randomized, placebo-controlled, double-blind, trial designed to ass...
