Alternative connecting pathway between the atriaRight and left atria (1/3 volume and muscle mass of the ventricles) pump blood to the ventricles. Chambers and Layers of the Heart 1. Six Second ECG Guidebook (2012), T Barill, p. 190 and the ventriclesThe larger chambers of the heart (3 times the volume and muscle thickness than the atria), responsible for the pumping of blood to the lungs and the rest of the body. (beside the bundle of HisPart of the AV junction, the bundle of His conducts the impulse through the fibrous plate that separates the atria and the ventricle; the bundle of His is also a pacemaker, firing at 40-60/minute. The bundle of His serves as...); resulting syndrome is called Woolf-Parkinson-WhitePre-excitation syndrome characterized by the early depolarization of the ventricle(s) via an accessory pathway (other than the AV junction) resulting in an early initiation of a QRS and possibly a Delta wave; due to the presence of the accessory pathway,... syndrome.
