Has anyone with severe anxiety/panic attacks experienced sudden racing heart? 

Usually I can calm myself down but this time I couldn’t and it was also pounding in my chest. I was worrying some but then I started feeling a burning pain in the center of my chest and started obsessing on it (I have health anxiety) so maybe that is what caused it? Anyways, it was between 120-150 depending how much I was worrying about it. I think I was feeding the flame but I’m not sure. 

So I called an ambulance and they told me I was having SVT. I have had numerous tests done, seen a cardiologist who put me on a holter monitor, and numerous doctors have all said sinus tachycardia likely caused by my severe anxiety/panic attacks. I told the paramedics this but they insisted that it was SVT because at this point my heart rate was between 150-190. Probably because they were scaring me about the SVT. So they wouldn’t listen and I was crying begging them to listen to me and wouldn’t. So they gave me adenosine, a medicine that stops your heart and snaps it out of SVT. Made my heart and body feel weird and they were like “OMG HER HEART RATE DIDNT GO DOWN. GIVE HER ANOTHER DOSE” And again I’m crying begging them not to because I don’t like it and I don’t have SVT. They give it to me and this time feels worse but still didn’t make my hr go down. FYI, adenosine doesn’t work for sinus tachycardia. They insisted on giving me another dose and I yelled at them to bring me to the hospital.

The ER doctor ran blood tests, took a chest X-ray, read my previous files and diagnoses, agrees that it is just sinus tachycardia. Gives me beta blockers, ativan, magnesium fluids, and potassium pills because my potassium was a little low. 

So today I am worrying maybe I do have SVT? Maybe there’s something actually wrong since it kind of came out of nowhere and I couldn’t get it to calm down. Has anyone or does anyone get the random racing high heart rate? Even when I feel less anxious than normal it can happen. Sorry for the ranting.
