WebIt is important to note that atrioventricular nodal blocking agents such as digoxin, β-blockers, adenosine, verapamil and diltiazem are contraindicated in pre-excited AF since they augment AP conduction, predisposing to ventricular fibrillation and sudden death. Pathway ablation offers a curative success rate of >95%. 1. WebThis case illustrates the typical ECG findings of a patient with Wolff-Parkinson-White syndrome both in sinus rhythm and pre-excited atrial fibrillation. Figure 3 clearly shows the short PR interval and delta wave (best seen in V4) classically described in Wolff-Parkinson-White syndrome. Figure 1 shows pre-excited atrial fibrillation.
