Abstract
This chapter discusses the philosophy of developing a constitutive equation for cardiac muscle based on uniaxial tests performed on papillary muscles. We begin with a background description of cardiac mechanics to highlight the methodological and procedural difficulties encountered in intact heart mechanics. The papillary muscle model is suggested as an alternative. Theoretical and experimental aspects requiring consideration in in-vitro papillary muscle mechanics are presented. The chapter concludes with the presentation of two constitutive equations; one describes the diastolic (passive) behavior of muscle, and the other describes its systolic (active or contractile) behavior.
