Initial ECG in the ED: Presenting ECG : Wide-complex tachycardia at a rate about 200. This is overwhelmingly likely to be ventricular tachycardia, even if only age and medical history are considered. Nevertheless, the widths of both the QRS complex and the RS duration are similar in both the old ECG and the tachycardia.

Another way that WPW can be concealed is in the very rare (~15% of all WPW patients) retrograde-only conduction, in which the accessory pathway ONLY allows retrograde conduction, which obviously wouldn't show a delta wave on sinus EKG but still predisposes the patient to re-entry tachycardias.
