Rv free wall strain 12 5 associated with greater disease.
Correctly measuring the wall thickness is an important step in the window ordering process here we show you just how easy it is to get this measurement.
15 16 still owing to the lower impedance and greater distensibility of the pulmonary artery bed the rv can pump blood at the same rate and volume as the lv.
