The relationship between myocardial oxygen consumption (MVO2) and the total pressure-volume area (PVA), which represents the total mechanical work performed during a cardiac cycle, has been shown to be linear and independent of loading conditions: MVO2=aPVA+b. When inotropic state is enhanced, the MVO2-PVA relation shifts upward (increase inb), and when inotropic state is depressed the relation shifts downward (decrease inb). However, thequantitative relationship between contractility andb (the… CONTINUE READING
