Dont worry. If your EKG and everything came back ok, you are not dying. It could definately be a
panic attack. I know it is super scary and makes you feel like your about to die, like your having a
heart attack or cant breath or something. Ive had them a few times. BUT, it may also be
PSVT. Maybe ask your doctor about looking into that. One day I was just getting ready to go out. I was in my early twenties and had never had this happen before. All the sudden, my heart had a sudden 'thud' in my chest and my heart just started racing. It felt like my heart would explode or beat right out of my chest! I called 911 and they told me to take my pulse. it was 150 beats per minute. not comfortable and pretty scary let me tell you. They put me in the hospital for a few days and did several tests, which all came back 'normal'. Eventually a cardiologist said he believed I had PSVT. This is basically when your heart does not register correctly. It does not receive signals and beat regularly all the time. Its most common and mine acts up most if in overly tired because my
adrenaline is pumping, which can trigger the rapid rate or a feeling of your heart 'flipping' or 'fluttering' in your chest - also a scary feeling. Its sort of takes your breath away for a second. So anyways, they put me on a
beta blocker. I am on Nadlol 20mg per day. At first, it did make me SO tired and my blood pressure was pretty low but they said this was normal and would pass. It did. After about 2-3 weeks, i started getting my energy back and now, im much better. I hardly ever have the heart flutters and I have not had the
rapid heart rate sine I began the medicine. You may want to ask your doctor about PSVT or look it up online and see if you think it sounds like what you experienced
