Hi,
I have a similar story. I never had a history of fainting in the past. I'm 24 years old and was sent to the ER after being found unconscious. I remember bits and pieces. I wasn't feeling good and decided to take mucinex because i was having chest congestion. An hour in of the night, my chest was pounding, side of my body was numbness, and loss of vision before I collapse on the floor. I was taking my birth control Sprintic After meeting with my primary doctor, she said I had a seizure. But my eyes wasn't rolled back. After feeling frustrated because I still was having chest pain, numbness all over the body, I went to the ER again to see a neurologist. All my blood work, blood clots, chest xrays and cat scan was negative. They told me I had syncope but couldn't describe the causes of it. I wonder if my birth control caused it? What is EFG? I don't want this incident to ever happened again. I wouldn't want Anyone to experience what I had. I went to the cardiologist and my heart rate test was normal. The doctor said only time will heal but I wonder if there are other tests I should take? What about Arrhythmias? Should i take a test for that? I'm just lost and not sure how to go about this. Thank you.
One other thing I forgot to mention; to keep from becoming dehydrated not only do you need to drink more, but you also need to eat protein as it is the protein that keeps the body hydrated. Also stay away from caffine in coffees, teas and sodas as caffine can cause dehydration.
I would certainly see your GP over this and from there see if you can get a referral to a cardiologist. When the heart beats too fast there is not enough time for the chambers to fill with blood which means blood does not get to the brain to the degree that it should which causes a person to become lightheaded as well as to pass out. The EKG in the ER would probably be normal because the possible arrhythmia that may have caused you to pass out has passed and the heart's normal electrical tracts have been reenstated. See a cardiologist and he may order a 24-72 hour Holter Monitor or a 30 day Event Monitor to see if they can figure out if arrhythmias are the problem
How are your eating habbits? I know at work sometimes it can be hard to prioritize eating and making sure you drink enough water, but in young girls, thats certainly one of the first things we think about with fainting spells. Do you exercise a lot and usually have a low blood pressure? I suggest making an appointment with your primary doctor so she can do more thorough blood work than the ER and she may have more insight as she knows your history. In the mean time what you can do is dont go from a lying to a standing position all at once, take time to sit in between. Also, when standing, do so slowly and not abruptly, as that causes all the blood to rush from your head to your feet, which can sometimes cause fainting. If you get that "auro" defineitly sit, if not lie down, and tell someone. Try as best you can to take it easy stress wise. Good luck to you, I hope this gets better!
