==Overview==
In up to one-third of [[patients]] with [[Wolff-Parkinson-White syndrome]], paroxysmal [[atrial fibrillation]] develops. Studies have been demonstrated that [[Wolff-Parkinson-White syndrome]] with a left lateral bypass tract has even a higher [[incidence]] of [[atrial fibrillation]]. On the other hand [[Wolff-Parkinson-White syndrome]] [[patients]] with right free wall accessory pathway have a lower chance of [[atrial fibrillation]] development. Development of [[atrial fibrillation]] in a [[patient]] with [[Wolff-Parkinson-White syndrome]] can result in [[Complication (medicine)|complications]] such as [[syncope]], [[ventricular fibrillation]] and ultimately sudden death. There are some hypothesized mechanisms for development of paroxysmal [[atrial fibrillation]] in [[patients]] with [[Wolff-Parkinson-White syndrome]], such as effects of accessory pathways on [[atrium]], spontaneous deterioration of [[AV reentrant tachycardia]] ([[AV reentrant tachycardia|AVRT]]) into [[atrial fibrillation]] and [[atrium|atrial]] [[Cardiac muscle|muscle]]'s electrical abnormalities. In [[Hemodynamics|hemodynamically]] stable [[patients]], [[Intravenous therapy|intravenous]] [[procainamide]] may be administered to convert pre-exited [[atrial fibrillation]] to [[sinus rhythm]]. [[Atrial fibrillation]] associated with a rapid [[tachycardia]] due to an accessory pathway may be treated with [[flecainide]] that has shown to slower the [[ventricle|ventricular]] rate by prolonging the shortest pre-excited cycle length during [[atrial fibrillation]] and hence terminate [[atrial fibrillation]].

**Spontaneous deterioration of [[AV reentrant tachycardia]] ([[AV reentrant tachycardia|AVRT]]) into [[atrial fibrillation]]
**Effects of accessory pathways on [[atrium]]
***Numerous studies have been reported a decreased [[incidence]] of [[atrial fibrillation]] in [[patients]] who undergone a successful ablation of accessory pathways.
**Possible [[atrium|atrial]] [[Cardiac muscle|muscle]]'s electrical abnormalities and increased [[atrium|atrial]] vulnerability (which is independent of the role that accessory pathways play)
***Since a fraction of [[patients]] experience [[atrial fibrillation]] even after a successful accessory pathway [[ablation]], it can be concluded that there are other mechanisms independent of accessory pathways that cause [[atrial fibrillation]] in [[Wolff-Parkinson-White syndrome]].
***More evaluation with [[atrium|atrial]] [[Endocardium|endocardial]] mapping demonstrated the possibility of [[atrium|atrial]] [[diseases]] (such as intrinsic [[atrium|atrial]] [[muscle]] abnormalities) in [[patients]] with [[Wolff-Parkinson-White syndrome]]. 
*Based on a study done on [[patients]] with [[Wolff-Parkinson-White syndrome]] with documented or induced [[atrial fibrillation]], effective refractory period of the accessory pathway was correlated with the shortest [[RR interval]] and [[ventricle|ventricular]] rate average.
*In [[Hemodynamics|hemodynamically]] stable [[patients]], [[Intravenous therapy|intravenous]] [[procainamide]] may be administered to convert pre-exited [[atrial fibrillation]] to [[sinus rhythm]].<ref name="pmid2229793">{{cite journal| author=Boahene KA, Klein GJ, Yee R, Sharma AD, Fujimura O| title=Termination of acute atrial fibrillation in the Wolff-Parkinson-White syndrome by procainamide and propafenone: importance of atrial fibrillatory cycle length. | journal=J Am Coll Cardiol | year= 1990 | volume= 16 | issue= 6 | pages= 1408-14 | pmid=2229793 | doi=10.1016/0735-1097(90)90384-2 | pmc= | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=2229793  }} </ref>

Overview

In up to one-third of patients with Wolff-Parkinson-White syndrome, paroxysmal atrial fibrillation develops. Studies have been demonstrated that Wolff-Parkinson-White syndrome with a left lateral bypass tract has even a higher incidence of atrial fibrillation. On the other hand Wolff-Parkinson-White syndrome patients with right free wall accessory pathway have a lower chance of atrial fibrillation development. Development of atrial fibrillation in a patient with Wolff-Parkinson-White syndrome can result in complications such as syncope, ventricular fibrillation and ultimately sudden death. There are some hypothesized mechanisms for development of paroxysmal atrial fibrillation in patients with Wolff-Parkinson-White syndrome, such as effects of accessory pathways on atrium, spontaneous deterioration of AV reentrant tachycardia (AVRT) into atrial fibrillation and atrial muscle's electrical abnormalities. In hemodynamically stable patients, intravenous procainamide may be administered to convert pre-exited atrial fibrillation to sinus rhythm. Atrial fibrillation associated with a rapid tachycardia due to an accessory pathway may be treated with flecainide that has shown to slower the ventricular rate by prolonging the shortest pre-excited cycle length during atrial fibrillation and hence terminate atrial fibrillation.

Atrial fibrillation in Wolff-Parkinson-White preexcitation syndromes

2014 AHA/ACC/HRS Guideline for the Management of Patients With Atrial Fibrillation (DO NOT EDIT)[19]

Wolff-Parkinson-White and Pre-Excitation Syndromes

Class I
"1. Prompt direct-current cardioversion is recommended for patients with atrial fibrillation, Wolff-Parkinson-White syndrome (WPW), and rapid ventricular response who are hemodynamically compromised. (Level of Evidence: C)"
"2. Intravenous procainamide or ibutilide to restore sinus rhythm or slow the ventricular rate is recommended for patients with pre-excited atrial fibrillation and rapid ventricular response who are not hemodynamically compromised. (Level of Evidence: C)"
"3. Catheter ablation of the accessory pathway is recommended in symptomatic patients with pre-excited atrial fibrillation, especially if the accessory pathway has a short refractory period that allows rapid antegrade conduction. (Level of Evidence: C)"
Class III: No Benefit
"1. Administration of intravenous amiodarone, adenosine, digoxin (oral or intravenous), or nondihydropyridine calcium antagonists (oral or intravenous) in patients with Wolff-Parkinson-White syndrome (WPW) who have pre-excited atrial fibrillation is potentially harmful as these treatments accelerate the ventricular rate. (Level of Evidence: B)"

(Level of Evidence: C)"
Class III (Harm)
"1. Intravenous administration of digitalis glycosides or nondihydropyridine calcium channel antagonists is not recommended in patients with Wolff-Parkinson-White syndrome (WPW) who have preexcited ventricular activation during atrial fibrillation. (Level of Evidence: B)"
Class IIa
"1. Intravenous flecainide or direct-current cardioversion is reasonable when very rapid ventricular rates occur in patients with atrial fibrillation involving conduction over an accessory pathway. (Level of Evidence: B)"
Class IIb
"1. It may be reasonable to administer intravenous quinidine, procainamide, disopyramide, ibutilide, or amiodarone to hemodynamically stable patients with atrial fibrillation involving conduction over an accessory pathway. (Level of Evidence: B)"
