association of paroxysmal tachycaria or atrial fibrillation and pre-excitation characterized by a short PR interval and a long QRS interval with a delta wave.
A type of ventricular pre-excitation resulting from the activation of an accessory pathway known as the Bundle of Kent. This pathway presents an abnormal electrical communication from the atria to the ventricles. Wolff-Parkinson-White syndrome is characterized by a short PR interval and a long QRS interval with a delta wave. (NCI)
