Which of the following is not true regarding Wolff-Parkinson-White (WPW) syndrome?

Wolff-Parkinson-White (WPW) syndrome Bundle of Kent is an aberrant anomalous path that connects SA node directly to the ventricles, bypassing the AV node. It is found in Wolff-Parkinson-White (WPW) syndrome There is no AV nodal delay. Hence, ventricular contraction stas very early, before its filling has occurs substantially. This will reduce the stroke volume In the absence of AV nodal delay, there is shoened PR interval on ECG. d ("delta") wave is seen on ECG; it results from the shoened PR interval.
