Related to ventricular systole: cardiac cycle, ventricular diastole


the contraction, or period of contraction, of the heart, especially of the ventricles, during which blood is forced into the aorta and pulmonary artery. adj., adj systol´ic.
atrial systole contraction of the atria by which blood is forced into the ventricles; it precedes the true or ventricular systole and is indicated by the fourth heart sound.
extra systole see extrasystole.
ventricular systole contraction of the ventricles, forcing blood into the aorta and pulmonary artery.

It has a wall adjacent to the left ventricle and acts a decompression chamber during left ventricular systole and during other periods when left atrial pressure is high.
Free wall contracts in a time distance after the septal contraction and the resulting time mismatch causes the septum to move away from the free wall during ventricular systole diminishing the septum's contribution to LV stroke volume.
There was a systolic bulging of the membrane and right-to-left shunting during ventricular systole. Slight enlargement of the right heart chambers was noted as well as increased pulmonary flow (Qp/Qs ratio--2.0).
In normal relaxation, the left atrial pressure decline during ventricular systole drives flow into the left atrium (peak systolic pulmonary vein velocity, S wave).
In the first case posterobasally located akinetic area showed relatively wide neck and paradoxical movement with ventricular systole. Aneurysmatic area in the second case, albeit larger, had also wide neck but its contractility was interpreted as akinetic.
LAV at the end of ventricular systole ([LAV.sub.max]), the smallest LAV after atrial emptying at the end of ventricular diastole ([LAV.sub.min] and the LAV at the onset of atrial emptying coincided with pre-p wave on the electrocardiography ([LAV.sub.pre-pw]) (23,27).
