atrioventricular nodal rhythm
Definition
- Noun:
- A specific type of heart rhythm: "atrioventricular nodal rhythm" refers to the normal, regular heartbeat that occurs when the heart's atrioventricular (AV) node is the primary pacemaker, controlling the rate and coordination of the heart's contractions.
Examples of Usage
- Noun:
- The electrocardiogram showed a stable atrioventricular nodal rhythm.
- In this condition, the atrioventricular nodal rhythm ensures the ventricles contract regularly.
Advanced Usage
- Medical Context: The term is used almost exclusively in clinical, cardiological, and physiological contexts to describe a specific cardiac electrical activity pattern.
- The patient's escape rhythm was identified as an atrioventricular nodal rhythm.
Variants and Related Words
- AV nodal rhythm (n): A common abbreviated form of "atrioventricular nodal rhythm."
- Junctional rhythm (n): A closely related term often used synonymously, though subtle clinical distinctions may exist.
Synonyms
- Junctional rhythm: A rhythm originating at the atrioventricular junction.
- AV junctional rhythm: Rhythm arising from the atrioventricular junction.
Related Phrases
- "Escape" atrioventricular nodal rhythm: Used when this rhythm emerges because the primary pacemaker (the sinoatrial node) fails.
- An escape atrioventricular nodal rhythm prevented cardiac arrest.
