Hi Meg
Yes, i sometimes have what i call "a biggy", which is probably a few in a row. It kinda makes me pause for a second or two and then i think its not going to stop. It does, and then i try to forget about it. I know it can be quite a scary weird sensation. I was also ECG'd etc and everything was good.
I think its pretty normal but scary none the less.
Take care
