Heart excitation originates in the sino-atrial node.
because of the vales in your heart
SA node- AV node- Bundle of His- Purkinje fibers
Valves opening and closing and blood flowingThe normal action of the heart, the pumping of the chambers and the closing of the valves.Closing of the valvesLub = closing the AV valvesDub = closing of the semi lunar valvesThe heart beats when the blood pumps
the aortaThe Aorta that originates from the left ventricle of the heart and extends down the spine before branching into two and so forth. It's about an inch in diameter.
The aorta.It originates from the left ventricle of the heart and extends down to the abdomen, where it branches off into two smaller arteries (the common iliacs).
The atrioventricular node is the site of heart excitation. It electrically connects and coordinates the atrial and ventricular chambers at the top of the heart.
the pacemaker area or the sinoatrial node
The excitation current is provided by a small self-excited pilot generator, attached to the same shaft as the alternator's rotor.
because of the vales in your heart

Maybe it originates in the Hebrew word LEV which means heart.
It originates there. First you breathe in and you add oxygen to you blood streams, by the way of capillaries. It then circulates from the heart to every where else.
Excitation theory is a misattribution of arousal.
SA node- AV node- Bundle of His- Purkinje fibers
Preventricular tachycardia is elevated heart rate the originates above the AV node.
