Atrial Fibrillation And Wolff-Parkinson-White Syndrome (Wpw)

Atrial fibrillation (AF) is a medical emergency with a WPW syndrome when the fast anterograde conduction via an accessory pathway occurs.

In a manifest WPW syndrome anterograde conduction over the accessory pathway takes place. developed a VHF, the normal frequenzlimitierende effect of the AV node is bypassed. The resulting extremely high Ventrikelfrequenzen (sometimes 200-240 beats / min) can pass into ventricular fibrillation (atrial fibrillation in the Wolff-Parkinson-White syndrome.) And cause sudden cardiac death. Patients with a concealed WPW syndrome are not at risk because their anterograde reconciliation does not take place via an accessory connection.

Tips and risks patients with atrial fibrillation and WPW should not take digitalis and calcium antagonists of the Nichtdihydropyridintyp (eg., Verapamil, diltiazem), since these drugs can trigger ventricular fibrillation. Atrial fibrillation in Wolff-Parkinson-White syndrome. The reaction of the ventricles is very fast (RR intervals of at least 160 ms). Shortly thereafter developed ventricular fibrillation (in lead II rhythm strip itself is continuously at the bottom). Therapy Gleichstromkardioversion is the treatment of choice. The usual rate lowering drugs used in VHF are not effective and digitalis and calcium antagonists of the Nichtdihydropyridintyp are contraindicated, since they lead to an increase in ventricular rate and can trigger ventricular fibrillation. If no cardioversion possible drugs can be administered to prolong the refractory period of the accessory connection. Procainamide i.v. or amiodarone here are the preferred medicaments, however, each antiarrhythmic Class Ia, Ic or III can be used.
