Frequency and Clinical Implications of Atrial Fibrillation in Patients with Accessory Pathways
Abstract
Abstract:Atrial fibrillation (AF) is a common arrhythmia associated with various cardiac conditions. This study investigates the frequency of AF in patients with accessory pathways, anomalous electrical connections that can lead to supraventricular tachycardia.
Objective:The primary objectives are to determine the prevalence of AF in patients with accessory pathways, identify associated factors, and assess the impact on clinical outcomes. A comprehensive dataset of 400 patients undergoing supraventricular tachycardia ablation at Hayatabad Medical Complex from 2020 to 2022 was analyzed.
Method:A retrospective study design was employed, utilizing patient records with documented accessory pathway(s) and complete clinical-electrophysiological data. Demographic information, clinical presentation, electrocardiographic and electrophysiological data, ablation procedures, and clinical outcomes were systematically collected. Analytical approaches included frequency calculation, comparative analysis, regression analysis, and outcome assessment.
Result:Out of 400 patients, 3.5% presented with AF at the time of accessory pathway ablation. Age was identified as a significant predictor of AF occurrence, with a mean age of 63.2 years in AF cases compared to 55.8 years in non-AF cases. Recurrence of arrhythmias was observed in 57.1% of patients with AF, emphasizing the need for ongoing monitoring and management.
Conclusion:This study contributes valuable insights into the relatively low prevalence of AF in patients with accessory pathways. While certain factors, including age, may be associated with AF, they do not serve as definitive predictors. Tailored management and adherence to guidelines are crucial for optimizing outcomes in this unique patient population. Future research may explore genetic factors and refine risk stratification models for a deeper understanding of AF in patients with accessory pathways.
