Diastole: meaning, definitions and examples
❤️
diastole
[ daɪəˈstoʊl ]
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.

Etymology
The word 'diastole' comes from the Greek word 'diastolē,' which means 'a drawing apart or a dilation.' It was first used in the context of the cardiac cycle in the early 19th century, as physicians began to better understand heart function and its phases. The distinction between systole (contraction) and diastole (relaxation) became crucial in the study of cardiovascular physiology. Medical researchers and practitioners utilized these terms to describe the mechanics of blood flow and heart activity, allowing them to advance diagnostics and treatment for heart conditions. As our understanding of the heart has developed, so too has the significance of diastole in the assessment of heart health.
