How Do You Spell PRESYSTOLE?

Pronunciation: [pɹɪsˈɪstə͡ʊl] (IPA)

Presystole is a medical term used to describe the period of cardiac muscle contraction that occurs just before the main contraction, or systole. The spelling of this word can be explained using IPA (International Phonetic Alphabet) phonetic transcription. The first syllable "pre" is pronounced as /pri/, the "syst" portion in the middle is pronounced as /sɪst/, and the final syllable "ole" is pronounced as /oʊl/.

PRESYSTOLE Meaning and Definition

1. Presystole is a medical term that refers to a phase in the cardiac cycle. It occurs just before the regular contraction of the ventricles, which is known as systole. Presystole is characterized by the contraction of the atria, the upper two chambers of the heart, in response to the electrical signals sent by the sinoatrial (SA) node.

   During presystole, the atria contract to squeeze the blood they have collected into the ventricles. This allows for the optimal filling of the ventricles before they contract, ensuring an efficient flow of blood through the heart. The contraction of the atria occurs after the P wave on an electrocardiogram (ECG) and before the QRS complex, which represents ventricular depolarization.

   Presystole is an essential part of the cardiac cycle as it ensures adequate blood supply to the body. If there are any abnormalities or disruptions in the presystolic phase, it can affect the overall function of the heart and lead to various cardiovascular conditions.

   In summary, presystole is the phase in the cardiac cycle when the atria contract to pump blood into the ventricles before their contraction. It plays a vital role in maintaining the efficient flow of blood and ensuring proper cardiac function.

2. The interval in the cardiac rhythm preceding the systole.

Etymology of PRESYSTOLE

The word "presystole" is derived from the combination of two Greek words: "pre" meaning "before" and "systole" referring to the contraction of the heart, specifically the contraction of the ventricles. In medical terminology, "presystole" is used to describe an abnormal contraction of the heart that occurs immediately before the normal systole.
