<unk><unk><unk>  <unk>  is a condition of pre-excitation of the ventricles of the heart due to the presence of an accessory pathway known as the Bundle of Kent through which the electrical impulses bypass the AV node.  The difference between<unk>  pattern and<unk>  is that<unk>  pattern is characterized by the presence of characteristic ECG findings, such as a short PR interval and a delta wave, whereas<unk>  is the occurrence of tachycardia with or without associated symptoms in a subject with existing<unk>  pattern.  The treatment of<unk>  is targeted towards the restoration of the sinus rhythm, usually by the administration of either ibutilide or procainamide.  The most common type of arrhythmia in<unk>  is AV reentrant tachycardia. Atrial fibrillation in a patient with<unk>  is life threatening and should be managed urgently.  Atrial fibrillation in a patient with<unk>  should be suspected when there is ECG findings suggestive of atrial fibrillation in the context of a heart rate higher than 220 beats per minute.
