I've been having heart palpitations since Halloween 09 it come along with fear of dying and high anxiety, the first 2 times it happened to me I took an ambulance to the hospital thinking the worst....they told me i was having panic attacks and prescribed me anti depressants and lorazapam , I stopped taking the depressants 2 months ago now because of not believing it was panic attacks I was having and continued to take lorazapam, then I started having some other symptoms, not at the same time as the palpitations but I have chest pain and I get stabbing pain going right through my heart, I have a echo cardiogram and it came back normal but I am still in disbelief, I went tot the gym with a girlfriend and 10 mins on the elliptical machine I was having the stabbing heart pain, I also have shortness of breath, heavy chest and it feels like my heart is working harder than normal,cough, my Dr. doesn't think there is anything wrong but had made me an apt to see a cardiologist anyways at the end of this month, I'm 28 years old and have 2 children and my husband is military and going over sea at the end of April, I'm terrified that I'm going to die, and I'm searching in the mean time for some sort of answers to help me but I don't really know what I'm looking for, please help!
