Frank starling heart failure

WebSummary. The Frank–Starling law (also known as Starling’s law of the heart) states that the strength of ventricular contraction is dependent on the length of the resting fibres. In … WebThe Frank-Starling mechanism is a compensatory response to heart failure that can support cardiac output but also worsen heart failure. Which statements regarding this mechanism are correct? Select all that apply. Increased oxygen demand produces ischemia. Excessive stretch on the ventricular wall will decrease preload.
