Aus Dornheim Anatomy
In the heart there is an autonomous excitation generation system (systema conducente cordis) and an excitation conduction system (systema conducente cordis). A distinction is made between four sections. When the heart is excited, the atrial and ventricular muscles contract about 100,000 times a day. The heart muscle is controlled by electrical impulses. The resulting impulses spread through a special cell system of the heart muscle.
