Atrial fibrillation involves multiple interatrial reentry circuits and the presence of accessory pathways congenitally between atrium and ventricle makes the condition even worse. Common triggering factors include rapidly discharging atrial foci, or atrial flutter. The common presenting features include palpitations, shortness of breath, and sweating and if not managed early may lead to syncope, ventricular fibrillation, and even death. A case of a young patient having no known co-morbidities, presented in cardiac emergency with electrocardiographic findings suggestive of atrial fibrillation with WPW syndrome. This case highlights the importance of early interpretation of electrocardiographic findings for proper treatment and management of such patients.
