Examples of diastole

• Contraction or systole is followed by a pause or diastole during which the blood flows from the veins into the auricles. 

• Later in its action, the drug depresses the intra-cardiac motor ganglia, causing prolongation of diastole and finally arrest of the heart in dilatation. 

• Nature outside man had taught him that life on all levels takes it course in a perpetual interplay of opposites, manifested externally in an interplay of diastole and systole comparable to the process of breathing. 

• This change of the colour of the wall he well ascribes to the compression of the retina by the diastole of the artery. 

• Thus we trace the rhythmic beating of the pulse to the systole and diastole of the heart, and we note a similar alternation in the contraction and relaxation of all our muscles. 

• 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.

• The jet was greatest during ventricular systole and was not seen during diastole.

• Velocities and integrals of forward flow in systole, early diastole and late diastole were measured; as was duration of pulmonary regurgitation.

• In young persons with compliant arteries, this wave arrives back to the aorta in diastole.

• As the ring is circumferential, it impedes the opening of the leaflet during diastole.

• Thus, early diastolic left ventricularfillingis impaired with redistribution of filling to late diastole and increased dependence on atrial systole.

• Inspiration, marked as an upward deflection on the respirometer, leads to marked augmentation of the passive forward flow during diastole.

• Velocities were lower than 200 cm/sec and never occupied die whole systole or diastole.
