Supplements for heart palpitations?

32 F, high pace job do ~10k steps a day, hike a lot, have history of Lyme, got heart pals after Covid. Have reduced coffee intake, increased water, stopped smoking weed. Still get them. Any ideas? Thanks

Update * I started taking calcium, magnesium, zinc supplement, Hawthorne and iodine salt and have had no palpatations since. After going to the doctor and having a heart monitor there were t any other conclusions to be noted.
