MeSH definition : A group of conditions in which HEART VENTRICLE activation by the atrial impulse is
faster than the normal impulse conduction from the SINOATRIAL NODE. In these pre-excitation
syndromes, atrial impulses often bypass the ATRIOVENTRICULAR NODE delay and travel
via ACCESSORY CONDUCTING PATHWAYS connecting the atrium directly to the BUNDLE OF
HIS.;
