<prompt> Which of the following is not true regarding Wolff-Parkinson-White WPW syndrome?No AV nodal delayDelta wave is seen on ECGProlonged PR intervalBundle of Kent  <response>: 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.
