So I had a pretty bad panic attack this morning, I get them every once in awhile but they used to be more frequent. This one had something different though…my heart rate was between 110-120 then suddenly I felt flushed and a brief sense of calm. This is where I noticed my heart rate dropped to 68…a rate that I typically only have when I’m laying down or sleeping. Then it crept back up in the span of 30 seconds or so to the 110 area. I’m just curious if anyone has experienced this before? 

Also some background, I’ve had heart tests (monitor, ecg, echo) 2 years ago and everything tested normal.
