“…However, due to the complexity of the underlying pathological mechanisms, AF recurs frequently after an initially successful ablation procedure. Reported frequency of LR ranges from 5 to 63%, depending on method and intensity of surveillance, technique used, patient characteristics, and definition of success, with a mean overall successful rate of approximately 70% [18]. In the present study, we found the cumulative LR was about 32.54% at a mean follow-up of 14.71 ± 8.58 months after a single procedure.…”

BackgroundLong-term recurrence (LR) is a tendency that re-occurs within 3 months after catheter ablation for atrial fibrillation (AF). Whether very early recurrence (VER) within 7 days of post ablation is a prognostic factor of LR or not is unclear. For this reason, present study sought to examine the relationship between VER and LR.MethodsIn this prospective analysis 378 consecutive patients underwent an initial catheter ablation for paroxysmal or persistent AF. The association between VER and LR was analyzed by univariate and multivariate Cox regression, as well as time-dependent receiver operator characteristic (ROC) analysis.ResultsAfter a mean follow-up of 14.71 ± 8.58 months, 81 (65.90%) patients with VER experienced LR and were associated with lower event of free survival from LR (Log rank test, P < 0.001). Multivariate Cox regression analysis revealed that VER (HR = 7.02, 95% CI = 4.78–10.31; P < 0.001), left atrial enlargement (HR = 2.92, 95% CI = 1.88–4.54; P < 0.001), tendency in advanced age (HR = 1.50, 95% CI = 0.99–2.28; P = 0.054), and tendency in male (HR = 0.71, 95% CI = 0.50–1.01; P = 0.060) were independent predictors of LR. According to time-dependent ROC analysis, it was found that VER was more sensitive than common risk factors in predicting LR (0.74 vs 0.66, P < 0.001) and combination model further improved the C statistic for predicting LR (0.82 vs 0.66, P < 0.001).ConclusionsAfter a single procedure of catheter ablation, patients with VER were strongly associated with LR and combination of VER and common risk factors could further improve prediction of patients who were at high risk for LR.

“…By this definition, SVT includes AF, flutter and even sinus tachycardia (Marine, 2007). Although some authors (rather confusingly) use SVT in this broad sense, most clinicians involved in arrhythmia management use the term to refer to a more specific type of rhythm.…”

“…In dual AV-node physiology, the AV node has two electrical pathways leading into it instead of one (Marine, 2007). Re-entry occurs when an atrial ectopic beat enters one pathway while the other is still refractory, and therefore unable to conduct.…”

“…7,13 Most tachycardias in patients with WPW syndrome (up to 95%) are reentry tachycardias, whose antegrade conduction is through the AV node/ His-Purkinje and retrograde conduction is through APs. 14,15 The QRS complexes are narrow, and the delta waves are not observed. Reentry tachycardia with antegrade conduction through the bundle of Kent is less common, and the QRS complexes are wide with delta waves.…”

“…2,23 PRESENTATION Patients with WPW syndrome and paroxysmal AF may present to a healthcare facility with palpitations, chest discomfort, shortness of breath, fatigability, or dizziness. 5,15 Those with sustained AF may demonstrate evidence of significant hemodynamic compromise with severe hypotension, dizziness, or syncope. 26 Some patients may present with full cardiopulmonary arrest if their rhythms deteriorate into VF.…”
