Do you speak (write) English? Most here are limited to communications in English. Even if you have limited English knowledge it will be the best choice for posting here.
I am sorry to say I don't even recognize what language you have posted in.
It's Spanish, and if my rusty skills are up to it, here is what he/she said:
"My name is Yasna and I am 27 years old. For a year, more or less, I have felt sporadic, brief, sharp pains on the left side of my chest, below the breast. The pain seems to disappear when I press on this area. And in general it comes on when I am at rest.
My EKG showed sinus tachycardia and an incomplete block of the 'right branch,' and these findings await confirmation by other tests.
I would like to know if this pain is related to my diagnosis, or if it is the result of tension or is muscular, as I have read. And also what measures I should take."
Alas, my Spanish isn't good enough to offer Yasna any advice in that language.
Yasna, puedes escribir en Inglés?
