If we can increase the rotational speed just in the diastolic phase, we may be able to control the amount of this backward flow. ... Related articles - All 3 versions

A chronic elevation in the diastolic filling pressure of the left side of the heart causes a backward transmission of the pressure to the pulmonary venous system which appears to trigger vasocon- striction in the pulmonary arterial bed. ...

We found that the duration of diastole could be set as a constant; however, the amount of backward flow can fluctuate due to the native heart con- dition in vivo. ...
