systole: Image:TorusSystoleLoop. png | Shortest loop on a torus The
systole of a compact metric space X is a metric invariant
Kaynak: Systolic geometryIn geometry , a
systole is a distance which is characteristic of a compact metric space which is not simply connected. It is the length
Kaynak: Introduction to systolic geometryThe second, "atrial
systole ," is when the atrium contracts, and blood flows from atrium to the ventricle. The third, "isovolumic
Kaynak: Cardiac cycleGiven a closed surface , its
systole , denoted sys, is defined to the least length of a loop that cannot be contracted to a point on the
Kaynak: Systoles of surfacesis the period of time when the heart refills with blood after
systole (contraction). Ventricular diastole is the period during which
Kaynak: DiastoleIt relates the
systole and the area of an arbitrary Riemannian metric on the 2-torus . Statement: Image:TorusSystoleLoop. png | Shortest
Kaynak: Loewner's torus inequalityIn differential geometry , Pu's inequality is an inequality proved by Pao Ming Pu for the
systole of an arbitrary Riemannian metric on
Kaynak: Pu's inequalityQ is furthermore the combined sum of output from the right ventricle and the output from the left ventricle during the phase of
systoleKaynak: Cardiac outputA dicrotic pulse is a type of pulse characterized by a percussion wave in
systole and a prominent dicrotic wave in diastole.
Kaynak: Dicrotic pulseSystolic heart murmurs are heart murmurs heard during
systole They can be classified by when the murmur begins and ends, between S1 and S2
Kaynak: Systolic heart murmurMüller's sign is the pulsation or bobbing of the uvula that occurs during
systole . It can be seen in patients with severe aortic
Kaynak: Müller's signIsovolumetric contraction is a term used in cardiac physiology to refer to an event occurring in early
systole , during which the
Kaynak: Isovolumetric contractionOliver's sign, or the tracheal tug sign, is an abnormal downward movement of the trachea during
systole that can indicate a dilation or
Kaynak: Oliver's signSimilar to the aortic valve , the pulmonary valve opens in ventricular
systole , when the pressure in the right ventricle rises above the

systole and diastole : During
systole , the ventricles contract, pumping blood through the body. During diastole , the ventricles relax
Kaynak: Ventricle (heart)Left atrial contraction (left atrial
systole ) (during left ventricular diastole) causes added blood to flow across the mitral valve
Kaynak: Mitral valveallowing uninterrupted venous flow to the heart during ventricular
systole By being partially empty and distensible, atria prevent the
