nodal rhythm
Definition
Noun: * The normal cardiac rhythm when the heart is controlled by the atrioventricular node: A specific, regular heart rhythm originating from the atrioventricular (AV) node, a group of specialized cells in the heart that act as a secondary pacemaker. This rhythm typically has a slower rate than the normal sinus rhythm.
Usage
This is a specialized medical term used in cardiology and healthcare contexts. It describes a particular physiological state or finding on an electrocardiogram (ECG).
Examples
- The patient's ECG showed a stable nodal rhythm following the procedure.
- A nodal rhythm often becomes apparent when the sinoatrial node fails to generate impulses.
- The cardiologist noted the presence of a nodal rhythm with a rate of 50 beats per minute.
Advanced Usage
- "Escape nodal rhythm": A protective nodal rhythm that emerges when the primary pacemaker (the sinoatrial node) is too slow or fails, preventing the heart from stopping.
- The term is often discussed in contrast to (the normal rhythm originating from the sinoatrial node) and other .
Variants and Related Words
- Junctional rhythm: A closely related and often synonymous term for nodal rhythm, as the AV node is located in the atrioventricular junction.
- AV nodal rhythm: An alternative phrasing explicitly naming the atrioventricular node.
- Nodal (adj): Pertaining to a node, especially the AV node (e.g., nodal tissue, nodal disease).
Synonyms
- Junctional rhythm
- AV nodal rhythm
- Atrioventricular junctional rhythm
Antonyms
- Sinus rhythm (the normal rhythm initiated by the sinoatrial node)
- Atrial rhythm (a rhythm originating elsewhere in the atria)
- Ventricular rhythm (a rhythm originating in the ventricles)
Noun
-
the normal cardiac rhythm when the heart is controlled by the atrioventricular node
