EP Device Implant v2.3 Education-Normal Conduction

Video Transcription

Video Summary

This video discusses the normal conduction of the heart and how abnormalities in the conduction system can lead to the need for a permanent pacemaker. The video explains that normal conduction starts with the activation of the SA node, which then transmits the signal across the atria and to the AV node. After a delay at the AV node, the signal travels through the bundle of His and splits into the right and left bundle branches, followed by the left bundle splitting into the left and anterior fascicles. Finally, the signal spreads into the Purkinje fibers in the ventricles, causing ventricular contraction. SA node dysfunction or AV node disease can disrupt this conduction system and necessitate a pacemaker implantation.
