- W2350838872 abstract "Objective The aim of this study was to predict the maintenance of sinus rhythm (SR) after cardioversion of atrial fibrillation (AF) by retrospectively observing the correlation between AF duration of P-wave measurements and left atrial function in patients with AF lasting less than 3 months.Methods We studied 98 consecutive patients who had undergone pharmacological or electrical cardioversion of the recent-onset AF during 2006 and 2008 with SR maintenance group (n:52) and AF recurrence group (n:46) at the end of 6-month follow-up.In addition to clinical features,P wave measurements and left atrial function were evaluated to predict the SR maintenance after successful cardioversion.Results At the end of 6-month follow-up,52 patients (53%) remained in sinus rhythm and 46 experienced recurrent AF,over a half of AF recurrence group relapsed within 2 week after cardioversion.There was no difference between patients with and without recurrence in gender,age,underlying heart disease,use of β-blocker,conversion pattern,left ventricular ejection fraction.There were significant difference between AF recurrence group and SR maintenance group in Pre-cardioversion AF duration (23.5±28.1 d Vs.1.2±1.3d,P0.01),spontaneous echo contrast (P0.01),left atrial dimension (47±3 mm Vs.41±3 mm,P0.01),Pmaxi、mum (P0.01) and P dispersion (53±4 ms Vs.40±5 ms,P0.01).In multivariate analysis,pre-cardioversion AF duration 7d (OR=2.61),left atrial dimension 45 mm (OR=2.10) and P dispersion 46 ms (OR=3.72) were independent predictors of SR maintenance,with an accuracy of 82%,83% and 86%,respectively.P maximum and spontaneous echo contrast were only univariate predictors.Conclusion Long AF duration,left atrial enlargement and prolonged P-wave dispersion can predict less successful SR maintenance after cardioversion in patients with AF." @default.
