Systolic Blood Pressure.
Pressure in aorta is greatest during ventricular systole.
ventricular systole
Extrasystole is an extra ventricular systole that happens during the begging of relaxation (repolarization). Since the cardiac is able to depolarize only after repolarization, any stimulus upon the repolarization period created an increased ventricular contraction or which is also called extrasystole but not a new contraction.
systolic pressure
When the ventricular pressure exceeds the pressure in the aorta and pulmonary trunk, the semilunar valves are forced open and blood is ejected out. This signals the ejection phase of the cardiac cycle of ventricular systole.
ventricular systole
increasing! :D
Systole is the phase during which the heart contracts resulting in the movement of blood to the peripheral parts of the body. The contractile force causes increase in the pressure of the arteries, greater than the diastole which makes it possible for the blood to reach the body.
Pressure in aorta is greatest during ventricular systole.
ventricular systole
In late diastole (relaxation phase), the semilunar (pocket) valves close, due to decreasing arterial pressure, to prevent blood flowing back into the ventricles. These stay closed during atrial systole. (But open again during ventricular systole.)Then, as the ventricles contract during ventricular systole, the bicuspid and tricuspid valves close to prevent blood from flowing back to the atria.So, it really depends on which phase of the contraction we are looking at.(Ed: format)
Systolic Pressure
diastolic blood pressure
systolic pressure
yes during ventricular systole AV valves are closed.
he cardiac cycle (heart beat) consists of cardiac muscle contraction (systole) and cardiac muscle relaxation (diastole). Blood pressure represents the force (pressure) exerted by blood against the arterial walls during a cardiac cycle. Systolic blood pressure, the higher of the two pressure measurements, occurs during ventricular contraction (systole) as the heart pumps blood into the aorta. After systole, the ventricles relax (diastole), arterial pressure declines and the heart refills with blood. The lowest pressure reached during ventricular relaxation represents the diastolic blood pressure. Normal systolic blood pressure in an adult varies between 110 and 140 mm Hg, and diastolic pressure varies between 60 and 90 mm Hg.
cardiac cycle Normal is less than 120 (mmHg)
