Abstract

Data characterizing the kinetics of the contraction of trabeculae and the intertrabecular tissue have been obtained. It has been concluded that trabeculae can act as conductors/transmitters of contraction across the myocardium and play a leading role in this process, while the functional role of the intertrabecular tissue is secondary and more passive, and consists in the optimization and support of the contractile process.
