Starling’s Law of the Heart. Increased EDV or myocardial fiber length results in increased SV or increased strength of contraction. Basis for Starling’s Law: P = 2T/r. where . P = pressure in ventricle or aorta at ejection. T = myocardial tension required to generate that tension.

3. Preload (Frank-Starling Law of the Heart) - critical factor for stroke volume is "degree of stretch of cardiac muscle cells"; more stretch = more contraction force. a. increased EDV = more contraction force. i. slow heart rate = more time to fill. ii. exercise = more venous blood return. 4. Contractility – contractile strength at given ...

38) The Frank-Starling law of the heart states that A) that increased filling time will decrease the force of contraction by the ventricles. B) the right and left ventricles must pump equal amounts of blood with each heart beat. C) a healthy heart will pump out all the blood that entered during the previous diastole.

__D – Ejection fraction is the lowest. In this case with a slightly elevated EDV, the Starling law of the heart would suggest increased contractility. Therefore predicted ejection fraction would be in the upper part of the normal range. This is a heart that is filling well (perhaps over …

= heart rate EDV = end diastolic volume. CO = (HR)(SV) ESV = end systolic volume. SV = stroke volume. Ejection Fraction: EF = ejection fraction EF = (EDV – ESV)/EDV ESV = end systolic volume. EDV = end diastolic volume. Flow through a tube: VF = volumetric flow. VF = vA v = velocity. A = cross-sectional area Darcy’s Law: MAP CO = cardiac output

Cardiac output is stroke volume multiplied times cardiac rate. Therefore, as ventricular contractility increases, stroke volume increases and cardiac output will increase. As preload (end diastolic volume) increases, the Frank Starling law of the heart states that …

In fact, diastolic arterial blood pressure (DBP) increased, and this led to an increase in both systolic (SBP) and mean (MBP) arterial blood pressures, thus maintaining the rest ventricle-to-aorta pressure gradient (see the Frank-Starling law applied to the heart).

Frank–Starling law - Wikipedia
Frank-Starling Law of the Heart. Preload, or degree of stretch, of cardiac muscle cells before they contract is the critical factor controlling stroke volume. Slow heartbeat and exercise increase venous return to the heart, increasing SV. Blood loss and extremely rapid heartbeat decrease SV.
