It relates to pre-excitation of the ventricles, and therefore often causes an associated shortening of the PR interval. It is most commonly associated with pre-excitation syndromes such as WPW.</p> <p>The characteristic ECG findings in <a href="https://litfl.com/pre-excitation-syndromes-ecg-library/">Wolff-Parkinson-White syndrome</a> are:</p> <ul> <li>Short PR interval (&lt; 120ms)</li> <li>Broad QRS (&gt; 100ms)</li> <li>A slurred upstroke to the QRS complex (the <strong>delta wave</strong>)</li> </ul> <p><a href="https://litfl.com/wp-content/uploads/2018/08/ECG-Wolff-Parkinson-White-WPW-Delta-wave.png"><img alt="ECG Wolff-Parkinson-White WPW Delta wave" loading="lazy" src="https://litfl.com/wp-content/uploads/2018/08/ECG-Wolff-Parkinson-White-WPW-Delta-wave.png"></a></p>
