This simulator demonstrates how changing ventricular filling volume (preload) shifts the heart along its Frank-Starling curve to produce a corresponding change in stroke volume.
Adjust the end-diastolic filling volume slider and watch how stroke volume responds, then compare a healthy curve to a flattened heart-failure curve to see how the same increase in filling produces different results.
A single slider controls ventricular filling volume while a toggle lets you switch between a normal and a heart-failure Frank-Starling curve.
The Frank-Starling mechanism still works in a heart that has been completely removed from the body and disconnected from all nerves, proving it is a property of the muscle itself rather than something the nervous system controls.
