Papillary muscle allows measurements too difficult or impossible to perform in whole hearts. Similarly, unlike single isolated myocytes, which represent the smallest fully functional model system, intact papillary muscle can be used to study cardiac function within a multicellular context and an intact 3-dimensional myofilament lattice. This video tutorial demonstrates clipping and loading of rat heart left ventricle papillary muscle for measurement using the IonOptix MyoClamp.
