Definition of systole in English:

systole

noun ˈsɪstəliˈsɪstəli

Physiology

The phase of the heartbeat when the heart muscle contracts and pumps blood from the chambers into the arteries.
〔生理〕（心脏）收缩（期）。常与DIASTOLE 相对
Often contrasted with diastole
Example sentencesExamples
- Younger people have a highly distensible aorta, which expands during systole and minimises any subsequent rise in blood pressure.
- The passive, elastic recoil between systoles maintains the blood pressure, smooths the flow of blood, and forces blood through the coronary arteries while the ventricles are filling.
- During systole, the rise from left ventricular end-diastole pressure to end-aortic diastolic pressure is decreased; thus the aortic valve opens earlier and stays open longer.
- 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.
- A newer classification scheme for heart failure is based not on left or right side failure but rather on whether the failure occurs during systole or diastole.

Derivatives

systolic

adjective sɪˈstɒlɪk

Physiology

Relating to the phase of the heartbeat when the heart muscle contracts and pumps blood from the chambers into the arteries.
〔生理〕（心脏）收缩（期）。常与DIASTOLE 相对
my doctor says my systolic pressure is too high
Often contrasted with diastolic
Example sentencesExamples
- They also recommend using both systolic and diastolic blood pressures for diagnosis and treatment at all ages.
- In addition, many patients with systolic dysfunction have elements of diastolic dysfunction.
- Pulse pressure was measured as systolic arterial pressure minus diastolic arterial pressure.

Origin

Late 16th century: via late Latin from Greek sustolē, from sustellein 'to contract'.
