Key result
Surface ECG fibrillatory wave characteristics in stable atrial fibrillation patients showed significantly greater interpatient differences compared to intrapatient differences over 24 hours (P<0.0001).
Why the study?
Are fibrillatory wave characteristics on surface ECG consistent within individual patients over 24 hours compared to differences between patients?
Population
20 clinically stable inpatients with atrial fibrillation
Design
Cohort
Follow-up
24 hours

May support intrapatient stability of fibrillatory waves over 24 h in stable AF; leaves open their utility for inferring atrial substrate.
Observational (n=20)
Are fibrillatory wave characteristics on surface ECG consistent within individual patients over 24 hours compared to differences between patients?
p-value: p=<0.0001
Fibrillatory wave characteristics on surface ECG are repeatable within individual patients over 24 hours, supporting their potential use for inferring underlying atrial pathophysiology.
Qin et al. (2004) conducted an observational in Atrial fibrillation (n=20). Surface ECG recording was evaluated on Interpatient versus intrapatient differences in fibrillatory wave characteristics (p=<0.0001). Surface ECG fibrillatory wave characteristics in stable atrial fibrillation patients showed significantly greater interpatient differences compared to intrapatient differences over 24 hours (P<0.0001).
