What is the condition suspected if an EKG shows shortened PR intervals, wide complex SVT with delta waves?

The presentation of shortened PR intervals, a wide complex supraventricular tachycardia (SVT), and the presence of delta waves on the EKG is highly indicative of Wolff-Parkinson-White (WPW) syndrome. This condition is characterized by an accessory conduction pathway that bypasses the normal delay at the atrioventricular (AV) node, allowing for rapid electrical conduction between the atria and ventricles.

The delta wave, which is a slurred upstroke in the initial part of the QRS complex, reflects this accessory pathway's influence during ventricular depolarization. The shortened PR interval occurs because the impulse travels through the accessory pathway rather than the slower AV node. This causes the heart to beat more rapidly, resulting in the observed wide complex tachycardia.

In contrast, other conditions listed would not typically present with both widened complexes and delta waves. While ventricular tachycardia also features wide complexes, it would not show the characteristic delta wave indicative of WPW. Atrial fibrillation would usually present with an irregularly irregular rhythm without a defined delta wave or shortened PR interval. Supraventricular tachycardia may show a narrow QRS when not influenced by an accessory pathway and wouldn
