I have had more stress lately ( new job, move, mother in law passed away) and have had anxiety attacks in the past. This past week I have noticed that when I sit in different positions or even standing I feel my heart beat/ race in my upper abdomen like by my stomach and even in my throat and then it s gone within a few seconds. It s really freaking me out. I m 27 female I m 5 5 and weigh 159. Is this an aortic aneurysm ??

Summarized question: What are the symptoms of aortic aneurysm?
