WebThe gradient is sometimes called the proton-motive force, and you can think of it as a form of stored energy, kind of like a battery. Like many other ions, protons can't pass directly through the phospholipid bilayer of the membrane because its core is too hydrophobic. WebMean pressure gradients have been shown to correlate better with gradients obtained during cardiac catheterization, and are generally used to assess the severity of a stenosis. The hypertrophic response to an obstructed outflow tract, however, is related more to the peak gradient than to the mean gradient.
