In the normal rhythm of the human heart an electrical impulse originates within the sinus node and courses by way of internodal pathways to the AY (atrioventricular) junction where it enters the AV node and passes to the His bundle for distribution through its right and left bundle branches ...
ScienceDirect Conduction System of Heart The cardiac conduction system is comprised of specialized “pacemaker” cells that spontaneously generate electric activity and conduction pathways that propagate it throughout the heart in a coordinated fashion, generating action potentials (APs) in individual cardiac...

Overview of the anatomy and functions of the heart. Heart (right lateral view) The heart is a muscular organ that pumps blood around the body by circulating it through the circulatory/vascular system. It is found in the middle mediastinum, wrapped in a two-layered serous sac called the ...
The heart contains structures consisting of atypical muscular tissue, the cells of which are poor in myofibrils and rich in sar-coplasm. The atypical muscular tissue forms the conduction system of the heart, which includes (1) the sinoatrial node, located in the wall of the right atrium, betw...

Conduction System of the Heart The heart is able to both set its own rhythm and to conduct the signals necessary to maintain and coordinate this rhythm throughout its structures. About 1% of the cardiac muscle cells in the heart are responsible for forming the conduction system that sets the ...
