Key result
The combination of fibrillatory wave amplitude and dominant atrial frequency from surface ECG correctly predicted electrical cardioversion outcome at 1 month in 85.71% of patients.
Why the study?
Can surface ECG parameters (f waves amplitude and dominant atrial frequency) predict normal sinus rhythm maintenance 1 month after electrical cardioversion in patients with persistent atrial fibrillation?
Observational
Can surface ECG parameters (f waves amplitude and dominant atrial frequency) predict normal sinus rhythm maintenance 1 month after electrical cardioversion in patients with persistent atrial fibrillation?
Surface ECG parameters, specifically f wave amplitude and dominant atrial frequency, show promise in predicting the success and 1-month maintenance of sinus rhythm after electrical cardioversion for persistent atrial fibrillation.
No takes yet. Share an insight, caveat, or question.
May support ECG-based prediction of cardioversion success in persistent AF; hypothesis-generating and requires prospective validation before practice change.
Alcaraz et al. (2009) conducted an observational in Persistent atrial fibrillation. Fibrillatory wave amplitude (fWA) and dominant atrial frequency (DAF) from surface ECG was evaluated on Prediction of atrial fibrillation recurrence 1 month after electrical cardioversion. The combination of fibrillatory wave amplitude and dominant atrial frequency from surface ECG correctly predicted electrical cardioversion outcome at 1 month in 85.71% of patients.
