Hi, I have a nine-year-old son who s experienced two instances of heart palpitations/fainting or feeling faint during the past weeks. First time it happened, he hit his head on a wall and we went to the hospital where he got three stitches. The doctor there didn t seem to think the fainting was anything to worry about, but now that it s happened again, I m a bit concerned. He s grown a bit over the summer and I was thinking that maybe that could cause low blood pressure and fainting. Also, he doesn t drink very much fluids unless forced to... Should I see a physician about the heart palpitations/faintings? Or wait and see how it develops while making sure he gets enough fluids? // Anna
