Heart excitation originates in the sino-atrial node.

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
A supraventricular tachycardia is tachycardia (heart rate > 100) that originates above the AV node, in the atria. There are several different forms of supraventricular tachycardia, including sinus tachycardia, atrial fibrillation, atrial flutter, atrial tachycardia, multifocal atrial tachycardia, and a nebulous condition called paroxysmal supraventricular tachycardia (PSVT). Many people also consider junctional tachycardia a supraventricular tachycardia.
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 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.

Excitation frequency can be calculated as the reciprocal of the excitation period, which is the time interval between two consecutive excitations. The formula is: Excitation frequency = 1 / Excitation period. Alternatively, if you know the excitation waveform (e.g., sine wave), you can determine the excitation frequency from the period of that waveform.
T-tubules in cardiac muscle help transmit electrical signals deep into the muscle cells, allowing for synchronized contraction of the heart muscle. This process, known as excitation-contraction coupling, ensures that the heart beats effectively and efficiently.
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.
Maybe it originates in the Hebrew word LEV which means heart.

Excitation theory is a misattribution of arousal.
