Spanish term

ondas anguladas

Spanish to English Medical Medical: Health Care Video-EEG
From Mexico.
Comments at the end of the Video-EEG report.

"El estudio Video-Electroencefalográfico se considera anormal grado II por la presencia de brotes de ondas theta anguladas y ondas agudas en la región fronto-temporal izquierda."

This has me confused: I assume "ondas agudas" refers to "sharp waves", i.e. high amplitude/short wavelength, so what then are "ondas anguladas"? Are they the opposite, and would this be "angled waves" or "angular waves"? To me that sounds synonymous with "sharp waves." Or are they "slow waves"? I mention this as it appears theta waves are associated with relaxation and slower brain activity.

I appreciate your help.

There's a distinction made in http://repositorio.uchile.cl/bitstream/handle/2250/131045/De...

Ok, well this is not exactly my area but...
Ondas agudas must be sharp waves, because from the definitions I have found, they have the same duration(70-200ms).
However, I have found some references to "sharp theta waves" ie theta frequency, sharp wave duration (I suppose). But then why would they use two different terms for "sharp"? (basically your original question, I know).
Some sources have grouped spikes (20-70ms) and sharp waves together as one group, in contrast to slow waves, so maybe "theta spikes" could be another option. Do they make reference to "spikes" using another word in the rest of the report?
Not exactly a definitive answer...
I will post the references I have looked at in case they are of use to you or others.

Yes It reads: "Lo anterior traduce en la presencia de actividad disfuncional e irritativa en la región previamente descrita."

Hi,

Is there a conclusion line/diagnosis/compatible with/something similar? That could help in determining the likely terms used to describe it.

Theta angle waves / Tetha angled waves / Waves at theta angle

Declined
When used to indicate angles, "theta" is an unknown (exactly like using "x" for the unknown in equations).
I believe one of the three will do, depending on syntax

Please see ref.
Example sentence:

In trigonometry, theta is a symbol commonly used to represent an unknown angle in the same way you might use x to label an unknown side or an unknown number in general.

Note from asker:
Sorry, I should have explained further, theta is a label designating waves are at the slower end of the spectrum of brain waves. The spectrum goes like this, from the highest frequency to lowest: Gamma, Beta, Alpha, Theta, Delta. Thanks.

Note from asker:
Thank you very much. Your first reference led me to this: https://es.wikipedia.org/wiki/Onda_aguda_al_vértex which is quite specific, and led me to vertex sharp waves. I think I'm getting there...
