Since 2010 every once in a while I will have this feeling in my chest like a fluttering. The first few ties It happened I was not under any unusably circumstances or stress and in fact was just sitting still watching tv. It has happend off and on sine then. i told one doctr about it and he said it was anxiety (even thought otd him it happens randomly even if Im relaxed or laying down) It would do it about oncce every 3 months or so. The lats physician I had tried to catch it on a ekg and his stethoscope both but did not. It hurts almost..well it feels like pressure. And it freaks me out BAD Im only 31..plus my boyfriend said he did hear it do it. But it wasnt a fluttering. He said it sounded like an extra beat. He has heard it 3 separate times. as I said "Hey its doing it come listen!" lol Yesterday it started doing it again..only it did it for a long period of time..usually it would only happen over the course of 10-15 min about 5 times..last night it did it for over an hour and again today. I feel so weak too..I had to lay down and could hardly talk because I was just suddenly wiped of energy. My grandma has a extra heart beat but she told me it was harmless, well if so why is she on meds for it? Im scared..I dont want to drop dead in front of my 2 year old! I do not have any insurance or a doctor at this time.
