Clinical, echocardiographic, and hormonal factors influencing spontaneous conversion of recent-onset atrial fibrillation to sinus rhythm.
The present study was designed to determine clinical, hormonal, and echocardiographic factors influencing spontaneous conversion to sinus rhythm of recent-onset atrial fibrillation (symptoms <6 hours). The most important predictor of spontaneous conversion was the time of onset of atrial fibrillation; patients who developed the arrhythmia during sleep had the highest probability of spontaneous conversion during the first 24 hours. A second predictor was the plasma concentration of atrial natriuretic peptide during the arrhythmia.
