Eksempler på systole

• The duration of the regurgitant flow varied but in no valves did it occupy the whole systole or diastole.

• For the great vessels and the arterial valves this was in systole.

• Venous waveforms in the inferior vena cava and ductus venosus are triphasic with peaks corresponding to maximum systolic velocity, maximum diastolic velocity and atrial systole.

• It is interesting, however, that they measured the diameter of the infundibulum during systole and could, therefore, have used undersized balloons.

• This conduit closes during atrial systole, but reopens through the rest of the cardiac cycle.

• For calculation of ejection fraction, the largest and smallest ventricular areas were taken as diastole and systole respectively.

• The maximum and minimum diameter of the infundibulum at the hinge point of the leaflets were obtained from different frames during diastole and systole.

• The peak velocities during left ventricular systole and diastole, their ratio, as well as of the reverse flow at end-diastole were calculated.
