Describes a novel, economically and technically advantageous in vitro muscle column preparation from the rat left ventricle for studying cardiac physiology.
Ullrick et al. (1956) studied this question. Muscle column preparation from rat left ventricle vs. Other types of isolated heart muscle preparations was evaluated on Excitability, extensibility, tension development, and oxygen consumption. A muscle column preparation from the rat left ventricle offers economic and technical advantages over other isolated heart muscle preparations for in vitro studies.
