Wolff-Parkinson-White Syndrome is characterised by all of the following, EXCEPT:

Correct option is C

Wolff-Parkinson-White (WPW) Syndrome is a pre-excitation condition due to the presence of an accessory conduction pathway (Bundle of Kent). Classic ECG features include a short PR interval, delta wave (slurred upstroke in QRS), and a wide QRS complex. "Salvador Dali sagging" is not a recognized ECG finding and is unrelated to WPW.
Explanation of options: (a) ✔ Wide QRS complex – Seen in WPW due to abnormal ventricular depolarization. (b) ✔ Delta wave – The hallmark of WPW, indicating early ventricular activation. (c) ✘ Salvador Dali sagging – Not a clinical or ECG term associated with WPW syndrome. (d) ✔ Short PR interval – Indicates early conduction through the accessory pathway.
