The present review is a historic perspective on cardiac muscle function. WebJul 4, 2024 · In Chapter 5.8, we learned about the Frank–Starling Law of the Heart: increased filling pressure stretches the heart and increases its force of contraction. Increasing the force of contraction expels more blood from the left ventricle, so that cardiac output increases when the preload increases.
