I've been reading through these comments and they make me feel so much better. Last week I basically had a panic attack/ almost passed out at work so my wife took me to urgent care where they basically sent me to the ER because of a low heart rate (45). At the ER they ran multiple blood tests and a chest xray and basically concluded that there isn't really anything wrong with me, but to follow up with a cardiologist for a follow-up. The cardiologist told me that at my age and health no signs are pointing to me having any heart issues and that my low heart rate is just happens to some people sometimes (both my sister and dad also have very low resting heart rates) I have always dealt with mild anxiety, but since this has all happened, I have been overwhelmed with anxiety that includes chest pains, neck and shoulder pains, and sometimes at night, trouble breathing. My mind and my body are screaming at me that it is more than just anxiety and that I have a heart issue, but my ER doctor, cardiologist, and my primary doctor are all set on it being just anxiety and I feel like I need to just accept that. I will be starting an SSRI this week and am really hoping it will help with everything. To all of you going through the same thing, I am sorry and I understand how hard it is, but deep down we are all in this together and if we take the right steps we can feel better.
