SA node triggers, sends signal to AV node and accessory pathway. AV node has a safeguard to slow the signal down so the ventricles can fill. Accessory pathway doesn’t have safeguard, meaning the signal can very quickly travel from the atria down, depolarizing the ventricles. This creates a slurred upstroke, as the P wave is closely coupled with the QRS. Once the signal gets through the AV node, it travels very quickly through the circuit of the heart and up the accessory pathway, creating a sharp downwards wave as the ventricles depolarize. .
