Implication
Prompt 4-week ECG monitoring may enhance arrhythmia detection after syncope or palpitations; extends observational data but leaves optimal timing open for RCTs.
Structured PICO
Does 4-week external ECG monitoring provide a high diagnostic yield in patients with unexplained syncope or palpitations?
P
Population
395 patients (57.7% females, mean age 56.9 ± 18.7 years, 28.1% with syncope, 71.9% with palpitations) enrolled within 1 month after unexplained syncope or palpitations after being discharged from emergency room or hospitalization without a conclusive diagnosis, from 10 European centres.
I
Intervention
4-week ECG monitoring by external high-capacity loop recorder storing patient-activated and auto-triggered tracings.
O
Outcome
Diagnostic yield (conclusive events with reoccurrence of syncope or palpitation with concomitant ECG recording, or events with asymptomatic predefined significant arrhythmias) over 4 weeks.surrogate
A 4-week external ECG monitoring provides a substantial diagnostic yield for unexplained palpitations and syncope, especially when initiated within 15 days of the index event.
