Phonetic Transcription

/ˈeɪ.tri.əl ˌdiːˌpoʊ.lə.rɪˈzeɪ.ʃən/

Meaning and Usage

Atrial depolarization refers to the electrical activation of the atria (the two upper chambers of the heart) during the cardiac cycle. This process is crucial for the proper functioning of the heart, as it leads to the contraction of the atria and the subsequent filling of the ventricles with blood. Atrial depolarization is typically represented on an electrocardiogram (ECG or EKG) as the P wave.

This term is more often used in written contexts, especially within medical, biological, and physiological discussions, due to its specificity and technical nature. It is frequently encountered in medical literature, research articles, and textbooks.

Example Sentences

1. Atrial depolarization is essential for effective heart function.

2. Translation: Преждевременная деполяризация предсердий важна для эффективного функционирования сердца.

3. The doctor explained the significance of atrial depolarization in his treatment plan.

4. Translation: Доктор объяснил значимость деполяризации предсердий в своем плане лечения.

5. In a healthy ECG, atrial depolarization is observed as a P wave.

6. Translation: На здоровом ЭКГ деполяризация предсердий наблюдается как волна P.

Idiomatic Expressions

While "atrial depolarization" itself does not commonly appear in idiomatic expressions, terms related to heart functions and rhythms often do. Below are several sentences incorporating such idiomatic expressions.

1. "To wear one's heart on one's sleeve" suggests showing your feelings openly, similar to how atrial depolarization signals the heart's activity.

2. Translation: "Носить сердце на рукаве" означает открыто демонстрировать свои чувства, так же как деполяризация предсердий сигнализирует активность сердца.

3. "Heart speaks louder than words" can imply that emotional signals, much like atrial depolarization in physiology, can convey true intentions.

4. Translation: "Сердце говорит громче слов" может подразумевать, что эмоциональные сигналы, подобно деполяризации предсердий в физиологии, могут передавать настоящие намерения.

5. "To have a heart of gold" refers to someone who is kind or generous, echoing the ideal rhythm and function of the heart, signified by proper atrial depolarization.

6. Translation: "Иметь золотое сердце" относится к человеку, который добр или щедр, отзываясь на идеальный ритм и функцию сердца, которые отмечаются правильной деполяризацией предсердий.

Etymology

The term "atrial depolarization" is derived from the following components: - "Atrial" comes from the Latin word "atrium," which means "entrance hall," referring to the atria as the entry chambers of the heart. - "Depolarization" is a combination of "de-" meaning "down," and "polarization," derived from "polar" which refers to electrical charge separation. In a biological context, it describes the process of restoring a balance from an active electrical state to a neutral state, facilitating the contraction of muscle cells.

Synonyms and Antonyms

Synonyms: - Atrial excitation - Atrial electrical activity

Antonyms: - Atrial repolarization (the process of returning to the resting potential) - Atrial quiescence (a state of inactivity)
