BACKGROUND Most positive inotropic agents increase cardiac contractility by increasing the amount of Ca2+ cycled with each beat. The additional amount of oxygen that is consumed by the heart to cycle this additional Ca2+ is believed to reduce myocard

Barium contracture tonically activates myocardium while preserving cellular integrity. We studied the metabolic and mechanical consequences of sustained Ba2+ contracture. We measured the time course of phosphocreatine (PCr), ATP, Pi, total phosphate,

The mechanical properties of the right and left ventricles (RV and LV) have previously been studied separately. However, because of differences in RV and LV architecture, geometry, and muscle mass, it is not obvious how the properties of the two cham
