RECURRENCE, CARDIAC ARRHYTHMIA
To determine whether immediate, enhanced (14 days) ambulatory ECG monitoring in acute unexplained syncope patients can:Decrease the number of episodes of self-reported syncope at 90 days, and 2 years compared with standard care monitoring.Decrease the time to detection of clinically significant cardiac arrhythmia compared with standard care monitoring.Increase the rate of detection of clinically significant cardiac arrhythmia at 90 days and 1 year compared with standard care monitoring.Increase the rate of ECG/symptom correlation at 90 days and 1 year compared with standard care monitoring.Demonstrate cost-effectiveness compared with standard care monitoring.Decrease the number of episodes of syncope identified in the medical records at 90 days, 1 and 2 years compared with standard care monitoring.Decrease the index hospital admission rate and duration of hospital stay compared with standard care monitoring.Decrease 90 days, 1-year and 2-year syncope recurrence rates (identified in the medical records and self-reported) compared with standard care monitoring.Increase patient satisfaction compared with standard care monitoring.Decrease the rate of 30 day, 1-year and 2-year all-cause death compared with standard care monitoring.In the intervention group, by reporting the timing of detection of clinically significant cardiac arrhythmia what is the optimum duration of acute ambulatory ECG monitoring.Increase the affect rate of diagnostic testing and therapeutic intervention.
