WebDec 3, 2002 · The discovery that end-diastolic volume regulates the work of the heart is generally credited to Ernest Henry Starling, who described this relationship in a series of papers between 1912 and 1914 1–4 and in his Linacre Lecture, which was given at Cambridge University in 1915 and published in 1918. 5 In these papers, Starling and his … WebThe Frank–Starling law of the heart (also known as Starling's law and the Frank–Starling mechanism) represents the relationship between stroke volume and end diastolic volume. The law states that the stroke volume of the heart increases in response to an increase in the volume of blood in the ventricles, before contraction (the end diastolic volume), when …
