WebBackground theory The cardiac muscle cells of the heart (called the myocardium) are tightly bound together in layers and encircle the blood filled chambers of the heart. When the heart contracts the myocardium encloses on the blood filled chambers and blood is propelled around the body. WebThe Frank–Starling Law describes the relationship between LVEDV and CO. According to the Starling Law, CO increases with increasing left ventricular preload until the left ventricle reaches excessive end-diastolic volumes. With excessive end-diastolic volumes, the CO does not change and may actually decrease.

WebDec 3, 2002 · Starling began his work on the mammalian heart to explain why cardiac output remains constant over a fairly broad range of arterial pressures, heart rates, and temperatures. 1,2 In 1914, Markwalder and Starling 2 stated that “… the rise of venous pressure [that accompanies increased demands on the heart] must be regarded as one …
