"An intricate network of reactions is involved in matching energy supply with demand in the heart. This complexity arises because energy production both modulates and is modulated by the electrophysiological and contractile activity of the cardiac myocyte. Here, we present an integrated mathematical model of the cardiac cell that links excitation-contraction coupling with mitochondrial energy generation. The dynamics of the model are described by a system of 50 ordinary differential equations. The formulation explicitly incorporates cytoplasmic ATP-consuming processes associated with force generation and ion transport, as well as the creatine kinase reaction. Changes in the electrical and contractile activity of the myocyte are coupled to mitochondrial energetics through the ATP, Ca21, and Na1 concentrations in the myoplasmic and mitochondrial matrix compartments. ..."

 *   CRAY          If the system is a Cray, set CRAY to 1, else    *
 *                 set it to 0. This is needed since the Cray has  *
 *                 non-standard include files, and the loader      *
 *                 expects names all upper case.                   *
 *                                                                 *
 *   UNDERSCORE    Set this to 1 if the system's Fortran77 expects *
 *                 C functions to have an underscore at the end of *
 *                 the name, and also the Fortran77 appends an     *
 *                 underscore on all Fortran subroutine names.     *
 *                 Otherwise set it to 0. If CRAY = 1, UNDERSCORE  *
 *                 is ignored.                                     *
