How Do You Spell DIASTOLE?

Pronunciation: [dˈa͡ɪəstˌə͡ʊl] (IPA)

The word "diastole" is spelled using six letters, but its pronunciation can be a bit tricky. In IPA phonetic transcription, it is pronounced as /daɪˈæstəli/. The "d" and "t" sounds are pronounced clearly, while the "i" and "o" sounds are short. The "a" sound, on the other hand, is pronounced as a diphthong (ai), making it distinct from the similar-sounding word "diabetes". "Diastole" refers to the relaxation or dilation of the heart's chambers, an essential part of the cardiac cycle.

DIASTOLE Meaning and Definition

  1. Diastole is a term used in the field of medicine and physiology to describe the second phase of the cardiac cycle, specifically referring to the relaxation of the heart muscles and the chambers of the heart. It is the period between two contractions or systoles, during which the heart ventricles relax, resulting in the filling of blood in the chambers. Diastole allows the heart to rest and obtain oxygenated blood supply from the coronary arteries.

    During diastole, the heart muscles relax, and the pressure in the ventricles decreases, allowing the blood to flow back into the heart and fill the chambers. It is essential for the heart chambers to be adequately filled during diastole to ensure an efficient cardiac cycle and subsequent contraction or systole.

    Diastole can be further divided into two phases: early diastole and late diastole. Early diastole is the initial relaxation of the ventricles, while late diastole is the period just before contraction, during which the atria contract and deliver the remaining blood into the ventricles.

    In a healthy individual, diastole accounts for approximately 2/3 of the cardiac cycle, while systole comprises the remaining 1/3. Any abnormalities or disturbances in the diastolic phase can have significant implications for the overall functioning of the heart and can lead to conditions such as diastolic dysfunction or heart failure.

    In summary, diastole refers to the relaxation phase of the cardiac cycle, allowing the heart to rest, refill with blood, and prepare for the next contraction.

  2. The dilatation of the heart cavities, during which they fill with blood; the diastole of the atria precedes that of the ventricles; diastole alternates rhythmically with systole or contraction of the heart musculature.

Common Misspellings for DIASTOLE

Etymology of DIASTOLE

The word "diastole" has its origins in ancient Greek. It is derived from the Greek word "diástolē" (διάστολή), which means "dilation" or "extension". This term was used to refer to the rhythmic expansion, or the relaxation phase, of the heart's chambers during the cardiac cycle. In modern medical terminology, "diastole" specifically relates to the period of relaxation and filling of the heart chambers.
