For the last 4 + months, my heart has been "skipping beats". I can tell when it happens because it is difficult to breath, I start sweating, I feel dizzy and very weak (sometimes I can't even walk). When I have an "episode" my BP is around 50. My heart never speeds up, it just beats very slowly and skipps every now and then. The episodes leave me feeling exhausted and some days are worse than others. I have no chest pain, I don't drink caffein, smoke, drink, or do drugs. I am 23 yr/old female who has a very healthy life style. These can't be PVC's because I have all these other symptoms, and I don't feel anxious at all. The episodes happen when I am out and about, laying around the house, or sleeping. What do you think is wrong with me??
