How do you manage your heart skipping beats?

Im a 26 year old male, i am no stranger to heart palpitations ive had them for many years. But they do get annoying at times, especially when i wake up in the middle of the night to go to the bathroom and my heart starts skipping alot just because i got up out of bed, it doesnt do this if ive slept for 8 hours only when i get up from sleeping for like 3 hours or so. Ive had afib 2 times caused by vomiting, my doctor is suspecting a hiatal hernia for all my heart palpitations and afib because i have some digestive issues including acid relux and abdominal discomfort after eating and sometimes even chest discomfort. But ive had 2 echocardiograms and ekg monitor for a few days and other tests like xrays and loads of blood work and i was told my heart is healthy anf not to worry. But of course i worry, but not only that i get annoyed with the palpitations. Hopefully i can get the digestive issues taken care of soon and maybe that will stop all this madness, also both of my parents have hiatal hernias and with my dad it caused svt especially after eating. So anyways sorry for all that, i just want to know ow to relieve them when they come on strong.
