tachogram
Very Low (Rare Technical Term)Technical/Scientific (Cardiology, Physiology)
Definition
Meaning
A graphic record of instantaneous heart rates (R-R intervals) over time, produced by a tachograph.
In broader medical or physiological contexts, any graphical record of rate, speed, or frequency of a biological process, though this is rare.
Linguistics
Semantic Notes
The term is highly specific to cardiology and physiological monitoring. It refers specifically to the output—the chart or tracing—rather than the device (tachograph) or the abstract measurement (tachycardia). It is not used in general contexts to refer to speed records of machines.
Dialectal Variation

Examples
By CEFR Level
- The doctor examined the tachogram to check the patient's heart rate variability.
- A tachogram is a specialised chart used in medical monitoring.
- The research paper included a detailed tachogram illustrating the arrhythmic episodes during sleep.
- Variability analysis of the 24-hour tachogram provided crucial diagnostic evidence.
Learning
Memory Aids
Mnemonic
Think of a TACHometer (speedometer) making a proGRAM or diAGRAM of your heart's speed.
Conceptual Metaphor
THE HEART IS AN ENGINE; its rate log is a tachogram.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'тактограмма' (tactogram) which relates to rhythm in music or linguistics.
- Avoid direct translation as 'тахограмма' unless in a strict cardiology context; it is not a general term for any speed diagram.
Common Mistakes
- Using it to refer to the device (correct: tachograph).
- Using it as a general term for any speed recording (e.g., of a car).
- Misspelling as 'tachygram' (which is not standard).

FAQ
Frequently Asked Questions
No, it is a rare technical term used almost exclusively in cardiology, physiology, and related research fields.
An ECG (electrocardiogram) records the heart's electrical activity. A tachogram specifically charts the timing between heartbeats (R-R intervals) to show heart rate variability.
No. While 'tachograph' is used for vehicles, the output is called a tachograph chart or record, not a tachogram. 'Tachogram' is reserved for physiological contexts.
In British English, /ˈtækə(ʊ)ɡram/. In American English, /ˈtækəˌɡræm/. The first syllable rhymes with 'back'.
