Despite the obvious increase in ventricular volume that occurs during atrial systole, there is no significant increment in intraventricular pressure.
Thus, early diastolic left ventricularfillingis impaired with redistribution of filling to late diastole and increased dependence on atrial systole.
Velocities and integrals of forward flow in systole, early diastole and late diastole were measured; as was duration of pulmonary regurgitation.
The jet was greatest during ventricular systole and was not seen during diastole.
In addition, during systole, a hypertensive right ventricle will deliver desaturated venous blood to the coronary arterial bed.
In these patients, the color flow jet was small, did not show any mosaic pattern, and occurred only in systole.
The peak velocities during left ventricular systole and diastole, their ratio, as well as of the reverse flow at end-diastole were calculated.
The maximum and minimum diameter of the infundibulum at the hinge point of the leaflets were obtained from different frames during diastole and systole.
