What syndrome is characterized by a short PR interval, delta wave, and AVRT?

Wolff-Parkinson-White syndrome is characterized by a specific set of electrical conduction abnormalities in the heart. The defining features of this syndrome include a short PR interval, which indicates that the electrical signal from the atria to the ventricles is conducted more quickly than usual due to the presence of an accessory pathway. The delta wave, which appears on the electrocardiogram (ECG), is indicative of this premature activation of the ventricles as they are excited through both the normal conduction pathway and the accessory pathway at the same time.

Additionally, the syndrome often leads to episodes of atrioventricular reentrant tachycardia (AVRT), where the electrical signals can create a loop involving both the atrioventricular (AV) node and the accessory pathway, resulting in rapid heart rates. The presence of these three components—short PR interval, delta wave, and AVRT—distinctively identifies Wolff-Parkinson-White syndrome among other cardiac conditions.
