The heart is a hollow, muscular organ in vertebrates responsible for pumping blood through the blood vessels by repeated, rhythmic contractions, or a similar structure in annelids, mollusks, and arthropods.
A few nights ago I woke feeling dizzy, nauseau, palpatation, severe sweating, I was awake at the rest of the night. MY bp was very high 183/107 I've spent the last few days slightly dizzy and nauseaus. I am wondering if I was near a heart attack, as there is cardiac history in the family, I have a weak left ventricle. What to people think? I have seen a doctor since but didnt mention the episode. I dont see my cardiologist until next year!
