During diastole , blood fills the veins and moves cephalad with each heartbeat.
Coronary blood flow occurs during diastole, and as the heart rate increases diastole shortens.
It relaxes slowly in early diastole and offers greater resistance to filling in late diastole , so that diastolic pressures are elevated.
Systole is that part of the heart's pumping cycle when it contracts and pushes blood out, the pulse if you like, and diastole is when the heart relaxes and fills with blood ready for the next heartbeat.
The reflected wave returns to the aorta during systole rather than diastole , increasing systolic work even more and reducing diastolic pressure, on which coronary flow depends.
Systolic and diastolic blood pressures were within normal limits.
Firstly, we analysed the diagnostic value of systolic and diastolic blood pressure and pulse rate with area under curves.
Only blood pressure, both diastolic and systolic, increased in anything resembling a similar pattern.
The numeric difference between your systolic and diastolic blood pressure is called your pulse pressure.
Men who experienced the Leningrad siege have higher systolic and diastolic blood pressure and excess mortality from ischaemic heart disease and stroke.
