    Gradient is the measurement of pressure created when the blood is 'blocked' from leaving the heart. A gradient of 9 is minimal. When gradients reach 30 it becomes a factor that can have an effect on ones over all health.
    Gradient over 50 had traditionally been the "gold standard" for surgical intervention. In recent years we have seen that number lowered to 30 if not responding to medical therapy.

    Hope this helps!

      hi everyone is gradient that same as pressures in your heart.I was told that my pressures were high,but not off the chart.just wondering thanks
      One day at a time.

        I believe you are asking the same yes. Pressures are measured in mm of mg( millimeters of mercury) same sensation of pressure as in an arm cuff for BP but you feel it or it is measured rather in your heart, ( not everyone feels the sensation of pressure) but maybe the symptoms resulting from this pressure in your heart. So you can imagine a gradient of 200+ is quite forcefull against the walls of the heart. It is called a gradient.

          In general terms, a pressure gradient is the change in the pressure measured across a given distance. In OHCM, this pressure change (the gradient) is related to the degree of the obstruction. Together with the pressure gradient there is a velocity gradient, i.e. a change in the velocity of the blood. Due to the obstruction, the velocity increases since there is a reduction in the flow area.
