autoregulation – heart will pump out volume received during diastole . . . CO=VR. Frank-Starling Mechanism of the heart. CO = VR ↑ in diastolic fiber length due to increase in VR allows greater contraction to expel extra fluid . also balances output between two ventricles. Electromechanical Coupling. electrical activity precedes mechanical ...
Heart Failure Pathophysiology
Right sided heart failure- can cause left-sided failure because it makes left side work harder. Congestion in peripheral veins. ... (aka Frank-Starling mechanism- counter productive) Reduction in tissue perfusion- activation of SNS and renin-angiotensin-aldosterone system- vasoconstriction and increase Na and H2O retention.

Frank-Starling Mechanism: the increased preload of dilation helps to sustain cardiac performance by enhancing contractility. ... cellular changes in hypertrophied hearts that initially mediates enhanced function may contribute to the development of heart failure.

Normally, the heart compensates for dilation with Frank-Starling mechanism but myocarditis can not do this due to inflammatory changes. This may lead to pulmonary edema and congestive heart failure. Clinical Manifestations. Precedent URI or gastroenteritis. Fever, fatigue, lethargy. Irritability. Feeding intolerance. Decreased heart sounds ...

In a transplanted heart, increased SV secondary to the Frank Starling mechanism and increased HR and contractility secondary to noradrenaline effect appear sequentially. The postponed HR acceleration at the exercise onset contributes to delayed CO adaptation, reduced O2 …
