Spanish term or phrase: ritmo beta de fondo
Hi everyone,

I came across this in a EEG examination report:

"EEG: ritmo beta de fondo, con una actividad de baja amplitud y alta frecuencia."

I'm not sure whether to translate "de fondo" as "background" or "substancial/significant etc."

I would appreciate your suggestions!

The target audience is in UK and there is no indication of where the report was published originally.

Thanks for your help,

background beta waves


Explanation:
"de fondo" in this context is more related to background and when it says "ritmo" it could also refer to "onda" or wave, as i am proposing. hope this helps

Example sentence(s):
  • todas las ondas cerebrales conocidas por la ciencia actual (Beta-Alfa-Theta-y Delta)
  • All the brain waves known to modern science (Beta, Alpha, Theta and Delta)

neutral  Joseph Tein: Hi Liz. The explanation does not show the use of the phrase "background beta rhythm." This could be correct, but there is almost no online confirmation of this usage (the first article I find is by a Russian).

Reference: Ritmo beta

Reference information:
From a downloaded document:

Ritmo beta
El ritmo beta es definido en base a su frecuencia: > 13 Hz, en general, 18-25 Hz. La actividad > 30 Hz tiene escasa amplitud y no suele ser registrada con técnicas convencionales. La amplitud es usualmente baja (5-10 μV); excepcionalmente supera los 30 μV, voltaje que es considerado anormal por muchos autores. De manera característica es simétrico en regiones homólogas de los dos hemisferios. La asimetría significativa (> 35%) o persistente suele deberse a factores extracerebrales (defecto óseo, alteraciones del cuero cabelludo, etc.) o es patológica. Un defecto óseo disminuye la resistencia al paso de la corriente eléctrica, originando un incremento de la actividad beta cerca o a distancia del mismo (ritmo de brecha).

I was going to suggest an answer but then had second thoughts! I think the key words are beta, activity and background.

Beta Activity
Beta activity is defined as a frequency of 13–30 Hz and is present in the background of most subjects. If completely absent it may represent an abnormality depending on other features of the EEG. Maximal beta amplitude is usually in the frontocentral regions, but it may be widespread. It does not respond to eye opening, as does the PDR. During drowsiness, beta may seem to increase in amplitude. This appears to be a function of amplitude diminution of other background frequencies and thus is more apparent than real.

https://www.sciencedirect.com/topics/nursing-and-health-prof...

Topics to be covered include the normal waking background rhythm (alpha
rhythm); beta activity; mu, theta, and lambda waves; activation effects on the EEG; and features of normal sleep.

5. BETA ACTIVITY
Beta activity (>13 Hz) is defined by three relatively distinct frequency bands: 18 to 25 Hz activity, which is the most frequently encountered; 14 to 17 Hz activity, which is less common; and the still rarer, greater than 25 Hz activity. The first two frequencies are seen commonly over the frontal regions and become more prominent as the subject gets drowsy. These two beta rhythms are usually of low voltage (
