atrioventricular bundle
Rare / TechnicalTechnical/Medical
Definition
Meaning
A specialized cardiac muscle fibre bundle that conducts electrical impulses from the atrioventricular node to the ventricles of the heart.
The sole electrical connection between the atria and ventricles, critical for coordinated heart muscle contraction; also known as the Bundle of His.
Linguistics
Semantic Notes
This is a highly specialized anatomical term. Its meaning is fixed within cardiology and anatomy; it has no metaphorical or general usage. It refers to a specific physical structure.
Dialectal Variation
British vs American Usage
Differences
No significant lexical or conceptual differences. The term is identical in both varieties, though British texts may historically show a slight preference for the synonym "Bundle of His."
Connotations
Purely technical/medical in both varieties. No cultural or stylistic connotations.
Frequency
Extremely low frequency in general discourse. In medical/academic cardiology, frequency is standard. No notable regional variation in frequency.

Examples
By CEFR Level
- The heart has special wires. One is called the atrioventricular bundle. (Simplified)
- A doctor might check if the atrioventricular bundle is working properly.
- Damage to the atrioventricular bundle can disrupt the electrical coordination between the upper and lower heart chambers.
Learning
Memory Aids
Mnemonic
Think: AV (like an audio/video cable) BUNDLE (like a bundle of wires). The AV Bundle is the heart's 'cable' carrying the electrical signal from the top chambers (atria) to the bottom chambers (ventricles).
Conceptual Metaphor
ELECTRICAL WIRING/CIRCUITRY OF THE HEART. The bundle is conceptualized as a specialized cable or conducting wire within the heart's electrical system.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating 'bundle' as 'пучок' in a general sense (like a bundle of sticks). In this context, 'пучок Гиса' is the precise, established term.
- Do not confuse 'atrioventricular' with separate terms 'atrial' and 'ventricular'. It is a single, compound adjective describing the connection *between* them.
Common Mistakes
- Misspelling: 'atrio-ventricular' (hyphen is optional but often omitted in modern medical writing).
- Mispronunciation: Stressing the wrong syllable in 'ventricular' (correct: ven-TRIC-u-lar).
- Conceptual: Confusing it with the atrioventricular *node* (AV node), which is a separate structure located just before the bundle.

FAQ
Frequently Asked Questions
Yes, they are completely synonymous terms. 'Bundle of His' is named after the Swiss cardiologist Wilhelm His Jr. who discovered it.
Not without medical intervention. A complete block of the AV bundle (third-degree heart block) stops electrical signals from reaching the ventricles, requiring an artificial pacemaker to sustain life.
It originates at the atrioventricular node in the lower right atrium, passes through the fibrous cardiac skeleton, and then divides into left and right bundle branches along the interventricular septum.
A general practitioner might use simpler terms like 'heart block' with patients. The specific term 'atrioventricular bundle' is more common among cardiologists, cardiac surgeons, and in detailed medical reports or education.
