Palpitations - is there anything that helps?

[Notthinkingclearly]

Been really bad for a few days. Feeling very stressed. Have been to Drs in the past and ECG normal. Does anyone have any home remedies. Slow breathing not working and it's getting worse now I am so aware of them. By myself with 2 children with high temperatures so can't go out.

I get palpitations sometimes (thanks menopause!) I hold my breath, drink something cold, stand by an open window (if it's colder outside) some or all of those usually sorts it out

Also, instead of feeling frightened, which just ramps up the anxiety, I get more annoyed with them in a 'what are you doing' kind of way
