systole contraction of the heart, during which blood is pumped into the aorta and the arteries that lead to the lungs Systole the contraction of cardiac muscle, or the myocardium. A systole consists of separate but successive atrial and ventricular contractions. The cardiac cycle comprises consecutive systolic and diastolic movement. In man, 75 heart beats per minute are accompanied by atrial and ventricular systoles that last 0.1 sec and 0.3 sec, respectively. Blood enters the ventricles from the atria during atrial systole and is ejected into the vascular system during ventricular systole. systole[′sis·tə·lē] (physiology) The contraction phase of the heart cycle. systoleenUK

[G. systolē, a contracting] systole (sĭs′tə-lē)n. The rhythmic contraction of the heart, especially of the ventricles, by which blood is driven through the aorta and pulmonary artery after each dilation or diastole.
sys·tol′ic (sĭ-stŏl′ĭk) adj.systole Cardiology Contraction of the heart, generally understood to be ventricular, with ejection of blood from the right ventricle into the pulmonary arteries and from the left venticle into the aorta Signs of left ventricular systole 1st heart sound, apical beat, arterial pulse. See Ejection fraction. Cf Diastole. sys·to·le (sis'tŏ-lē) Contraction of the heart, especially of the ventricles, by which the blood is driven through the aorta and pulmonary artery to traverse the systemic and pulmonary circulations, respectively; its occurrence is indicated physically by the first sound of the heart heard on auscultation, by the palpable apex beat, and by the arterial pulse. systole The period during which the chambers of the heart (the atria and the ventricles) are contracting. Atrial systole, in which blood passes down into the ventricles, precedes the more powerful ventricular systole in which blood is driven into the arteries. Systole alternates with a relaxing period called DIASTOLE.systole see HEART CARDIAC CYCLE.sys·to·le (sis'tŏ-lē) Contraction of heart, especially of ventricles, by which blood is driven through aorta and pulmonary artery to traverse systemic and pulmonary circulations, respectively. systoleenUK
