WebThe explanation to the Frank-Starling mechanism given here is somewhat out-of-date and probably not correct. It would have been better to present the original findings - i.e. Starling's Law of the Heart made using Newell Martin's isolated heart-lung preparation (the 'Baltimore method'). The original observations of stretch producing increased ... Weba curve called a Frank-Starling performance curve can be created by plotting left ventricular end-diastolic volume (or pressure) -- i.e. preload -- versus left ventricular cardiac output -- LV performance.

The Frank-Starling mechanism allows the cardiac output to be synchronized with the venous return, arterial blood supply and humoral length, [2] without depending upon external regulation to make alterations. The physiological importance of the mechanism lies mainly in maintaining left and right ventricular … See more The 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 … See more The Frank-Starling mechanism occurs as the result of the length-tension relationship observed in striated muscle, including for example skeletal muscles, arthropod muscle and See more The Frank–Starling law is named after the two physiologists, Otto Frank and Ernest Henry Starling. However, neither Frank nor Starling was the first to describe the relationship between the end-diastolic volume and the regulation of cardiac output. The first … See more Premature ventricular contraction Premature ventricular contraction causes early emptying of the left ventricle (LV) into the aorta. Since the next ventricular contraction occurs at its regular time, the filling time for the LV increases, causing an increased LV end … See more • Starling equation See more Web23 Dec 2024 · The Frank-Starling curve explains the relationship between stroke volume/cardiac output and left ventricle end-diastolic pressure (LVEDP) or pulmonary capillary wedge pressure (PCWP) in which there is … WebCompen satory factors like hypertrophy or the Frank-Starling mechanism may maintain the overall pump function of the ventricle, despite a defect in the underlying myocardial contractility.
