Okay, this "thing" has been happening to me lately, only the last two days. So I hope someone can shed some light.
I will have this period of time, I would say each one lasted about ten to fifteen minutes where it feels like my heartbeat suddenly takes off and start beating overtime, almost like my heart is working too hard. And then it goes away and things go back to normal again. I do have some anxiety and some heart concerns but I don't believe this is anxiety.
I do have heart disease, I have never had heart pain after my heart stent anyway. It seems to be a heart rhytum thing.
Can someone help me to identify this feeling?
