So, I had to go to the ER last weekend because my heart rate was in the 130's and my blood pressure was around 210/130. I talked to a cardiac specialist and he thinks I have POTS. Basically, my body can't adjust to the changes when I go from lying to sitting or sitting to standing. So, it causes my heart to go into tacycardia (spelling?). Thankfully, it is not anything life threatening or too dangerous. So, right now, I just have to cut all caffeine out of my diet and increase my salt intake. Thank God they don't think it's anything more serious since I'm only 27!
