“…The investigation for Wolff-Parkinson-White (WPW) syndrome in adults was numerous, but only limited information for children was noted. [1][2][3][4][5][6][7][8][9][10][11] This study was designed to evaluate the specific electrophysiologic characteristics and the outcome of radiofrequency (RF) catheter ablation in children with WPW syndrome. This will be helpful in the diagnosis and management of cardiac arrhythmias in children.…”

“…Strands of myocardium were seen within the typically insulating brous AV annulus, suggesting that accessory routes probably arise during embryologic development as a result of improper AV ring development. (2) The majority of the time, the APs conduct impulses in a non-decremental fashion, which means they are unable to decrease the quantity of impulses they send to the ventricles per unit of time. In contrast, the AV node's decremental conduction only permits a limited number of atrial impulses to reach the ventricles each period.…”

Background: Atrial fibrillation with accessory pathway can present with confounding ECG findings leading to inaccurate diagnosis sometimes leading to fatal outcomes. Treatment with AV nodal blockers is contra-indicated in pre-excited atrial fibrillation as it can lead to fatal ventricular arrythmia. Case Presentation: A 72-year-old female presenting with acute onset palpitations, chest discomfort, shortness of breath and light-headedness with similar past episodes was initially diagnosed to have atrial fibrillation. An ECG after metoprolol administration revealed the features of pre-excitation and Wolff-Parkinson-White syndrome. A repeat episode of tachyarrhythmia was terminated with electrical cardioversion and patient was followed-up in cardiology for radiofrequency ablation. Conclusion: A bizarre ECG with irregular wide complex tachycardia with QRS of varied shape and amplitude and sustained rates surpassing 200 beats per minute, suspicion of WPW syndrome with pre-excited AF should be considered. It is difficult to distinguish from polymorphic ventricular tachycardia, although electrical cardioversion is the primary therapy when hemodynamically unstable.

Propafenone is a sodium channel blocking antiarrhythmic drug. It also has beta-adrenergic, potassium channel, and weak calcium channel blocking activity. The drug is metabolized in the liver with rates dependent on the debrisoquin phenotype. The saturable metabolism results in nonlinear pharmacokinetics. The metabolites retain sodium channel blocking activity but little beta-adrenergic blocking activity. Both controlled and noncontrolled studies have documented its efficacy in a variety of supraventricular arrhythmias. Intravenous propafenone is effective in converting atrial fibrillation to normal sinus rhythm. Chronic oral administration decreases the frequency of recurrence of atrial fibrillation and paroxysmal supraventricular tachycardia. The drug is particularly effective in the Wolff-Parkinson-White syndrome. The drug may produce SA block in patients with underlying sinus node dysfunction. Propafenone has comparatively few noncardiac side effects. It is a useful primary drug or an alternative to more commonly used drugs used for the treatment of supraventricular arrhythmias.
