In-between episodes there is normal electrical conduction in the heart. During an episode of AVRT caused by<unk> , the accessory pathway conducts electrical activity from the ventricles directly back to the atria at the end of systole, which triggers the atria to contract, and the current to pass back to the ventricles again via the atrioventricular node (AV node); see diagram.
