My heart stopped but I thought I was just having anxiety

I couldn't breathe. I was having a panic attack but something was different this time. Usually my daughter could calm me but not even she could get me to breathe and calm my nerves. So I told her to call 911. They came in and I told them just to check my heart and make sure it was okay because I was having a panic attack and I just needed a Xanax so I asked them can you give me a Xanax and they said let us check your heart first. So they did nice and man it's amazing you're talking right now and your heart rate is 22. I said what does that mean they said you technically should be passed out right now we need to get you to the hospital. So they did and my daughter followed in the car and I got to the hospital and they brought me back and started working on me and told my daughter to go home everything would be fine like it always was and then she left and my heart stopped just stopped and I remember hearing charge and they put the paddles on me and that's the last thing I remember so they brought me back and then I was in the hospital for 4 days before they put a pacemaker in me told me they couldn't get my heart rate above 30 so I was 39 with something beating my heart and I hated it
