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.
