My severe cardiac anxiety all started with one severe panic attack that made me feel as if I could not breathe. After that event, I grabbed a pulse oximeter from CVS and began to monitor my oxygen levels a very unhealthy amount. Eventually this started to spread into focusing on the other number on the pulse oximeter, which was my heart rate. I noticed that my heart rate bounces around frequently. For example, within the span of one minute my heart rate will go from 85, 67, 78, 94, 105, etc. This eventually has led to an insane increase in my insanely specific heart palpitations in which I do not feel a "thump" like others. Mine feel like a drop on a rollercoaster. It almost feels as if my throat is being pulled into my stomach. During this time, I develop temporary shortness of breath and start to panic. Doctors have told me that both my blood tests and ekgs look normal. Still I find that I need more tests. I see a cardiologist on June 1st to try to dig deeper into this terrible situation I am having. Due to this, I have become slightly dependent on Xanax, which I have taken every day for the past two months. Driving has become a nightmare for me in particular due to this. I am constantly checking my pulse, taking ekgs on my Apple Watch, and searching my symptoms on google (bad idea I know haha). I just created an account on here to see if anyone else has had a similar experience to this. I will follow through with a cardiologist nonetheless, but it would mean the world to me if there was someone else out there with a similar experience that has had success in beating this.
