During a Stokes-Adams syndrome attack, total A-V block suddenly begins. After a few seconds, some pa of the Purkinje system beyond the block, usually in the distal pa of the A-V node beyond the blocked point in the node, or in the A-V bundle, begins discharging rhythmically at a rate of 15 to 40 times per minute and acting as the pacemaker of the ventricles.
