The normal cardiac conduction system delivers the electrical impulse to both the right and left ventricles simultaneously; however, in the presence of a left bundle branch block or right bundle ...

The impulse is then passed to another node within the heart – the atrioventricular node (AVN). This node is in the lower part of the right atrium.

However, this short-term regulation did not explain why the heart conduction system generally slowed down at night. “All the arrows pointed to the fact that there might be an intrinsic rhythm with the ...

“If Lynn’s heart starts beating too fast or is out of rhythm, this implantable defibrillator will shock it back into normal ...

Thus, normal conduction of an electrical impulse through the atrioventricular, or AV, node, then to the ventricles via the His-Purkinje system, is fast and results in a normal QRS duration.
