| − | + | The Frank-Starling mechanism describes how the [[kardial/en|cardiac]] ejection volume depends on the changes of pulse, [[Vorlast/en|preload]] and [[Nachlast/en|afterload]]. If, for example, a person stands up, the preload is reduced in the short term, which is automatically answered with a lower pumping capacity. However, if, for example, physical exercises lead to a higher [[Venös/en|venous]] supply, i.e. more venous blood in front of the [[Atrium,_Vorhof/en|atria]], the heart reacts accordingly with a stronger [[Auswurfleistung/en|ejection fraction]]. | |
