Diastole: meaning, definitions and examples
❤️
diastole
[daɪəˈstoʊl ]
Definition
medical term
Diastole refers to the phase of the cardiac cycle when the heart muscle relaxes after contraction. During diastole, the chambers of the heart fill with blood, preparing for the next contraction. This phase is crucial for ensuring that the heart can receive sufficient blood supply, maintaining effective circulation throughout the body. Diastole typically occurs between heartbeats, and its duration can be influenced by factors such as heart rate and blood pressure.
Synonyms
cardiac diastole, relaxation phase.
Examples of usage
- During diastole, blood flows from the atria into the ventricles.
- Cardiologists monitor diastole to assess heart function.
- Elevated heart rate can shorten the duration of diastole.
- Diastolic dysfunction can lead to heart failure.
Interesting Facts
Etymology
- The word 'diastole' comes from the Greek word 'diastole', meaning 'expansion' or 'dilation'.

Science
- During diastole, the heart's chambers – the atria and ventricles – fill with blood, preparing for the next contraction.
- This phase lasts longer than systole, about 70% of the cardiac cycle in a resting heart.
- Proper diastolic function is crucial for effective blood circulation and overall heart health.
Health
- Disturbances in diastolic function can lead to heart failure and other cardiovascular problems.
- Monitoring diastolic pressure is essential for understanding blood pressure and heart function.
- Athletes often have enhanced diastolic function, which contributes to their efficient heart performance.
Literature
- Diastole as a concept often appears in poetic forms, metaphorically representing rest or pause in rhythm.
- In literature, the heart's rhythmic phases are used to evoke emotional states, with diastole symbolizing tranquility.
Pop Culture
