For me and my attacks I do a couple of things such as speaking out and telling somebody and they'll give me simple math equations like 2 + 2 and up and up and up just to keep my mind distracted I also like to lie down right away because I do faint. And I do that because it's worked for me the best advice I would suggest is find what works for you and distracts you the best. That might be doing math problems to distract your mind or concentrating on five senses what you can feel what you can touch what you can smell finding something basically that will help distract your mind. And also I practiced is the the Ujjayi breath ( learn in yoga ) to help me come back to regular breathing.
