However, if there is any doubt about the diagnosis of orthodromic AVRT or if aberrant conduction leading to a wide complex QRS is observed, it may be prudent to manage as undifferentiated wide complex tachycardia. People with atrial fibrillation and rapid ventricular response may be treated with amiodarone or procainamide to stabilize their heart rate. Procainamide and cardioversion are accepted treatments for conversion of tachycardia found with WPW. Amiodarone in atrial fibrillation with WPW, is linked to ventricular fibrillation, and thus may be worse than procainamide.AV node blockers should be avoided in atrial fibrillation and atrial flutter with WPW or history of it; this includes adenosine, diltiazem, verapamil, other calcium channel blockers, and beta blockers. They can exacerbate the syndrome by blocking the hearts normal electrical pathway (therefore favoring 1:1 atrial to ventricle conduction through the pre-excitation pathway, potentially leading to unstable ventricular arrhythmias). Catheter ablation
The definitive treatment of WPW is the destruction of the abnormal electrical pathway by catheter ablation. Two main types of catheter ablation include radiofrequency ablation with heat or cryoablation with cold energy. This procedure is performed by cardiac electrophysiologists and has high success rate in the hands of an experienced electrophysiologist. Findings from 1994 indicate success rates of as high as 95% in people treated with radiofrequency catheter ablation for WPW. If radiofrequency catheter ablation is successfully performed, the condition is generally considered cured. Recurrence rates are typically less than 5% after a successful ablation.
Some patients, such as the ones with underlying Ebsteins anomaly and inherited cardiomyopathies, may have multiple accessory pathways. History
The bundle of Kent is eponymously named for British physiologist Albert Frank Stanley Kent (1863–1958), who described lateral branches in the atrioventricular groove of the monkey heart (erroneously believing these constituted the normal atrioventricular conduction system).In 1915, Frank Norman Wilson (1890–1952) became the first to describe the condition later called Wolff–Parkinson–White syndrome. Alfred M. Wedd (1887–1967) was the next to describe the condition in 1921. Cardiologists Louis Wolff (1898–1972), John Parkinson (1885–1976) and Paul Dudley White (1886–1973) are credited with the definitive description of the disorder in 1930.
