0 the phase during the beating of the heart when its muscles relax and its chambers fill with blood. -- diastol
The duration of the regurgitant flow varied but in no valves did it occupy the whole systole or diastole.
Patients having transannular patches, therefore, were classified into two groups according to the velocities of forward flow in the pulmonary arteries during late diastole.
Flow in die descending aorta was abnormal, with retrograde flow in diastole at die level of the diaphragm.
The horizontally-hatched area is the pressure generated during cardiac ejection, while the vertically-hatched area is the pressure maintained during the diastole.
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.
Those factors reducing aortic diastolic pressure, or shortening diastole, will compromise this flow.
