This means that it gives a highest value rather than an average.

The rv generates less pressure and therefore the index also lower with an average at around 0 28.
Right ventricular systolic pressure rvsp in echo is obtained by simply measuring the pressure gradient of the tricuspid regurgitant jet.
Remember though that the right ventricular systolic pressure estimate on the echocardiogram gives a peak and not a mean pressure.
Due to the high pressures which must be generated by the lv the isovolumic times of the lv are relatively long.
