Interesting--I have the same problem. I was diagnosed with Afib about 3 years ago--no other treatment recommended because I guess the Afib wasn't frequent enough(I am also on Eliquis and Metoprolol). I have found that if I have palpitations and start checking and feeling my pulse, etc., it makes it worse due to anxiety. So at my last yearly cardiology appointment, I asked my cardiologist if I could wear a heart monitor again(haven't for a could years). The report just came back, and I had frequent minor arrhythmias. I purchased a Kardia but haven't used it yet. My plan to help with the arrhythmias is to pray, exercise, drink more water, and work on relaxation(and try to ignore them). My cardiologist said that I could increase my Metoprolol to 50 mg daily if the palpitations are bothersome, but I choose to stay at 25 mg due to the side effects(I might take another 1/2 tab at another time of day if they bother me too much). The week I wore the heart monitor was a bad week, but the week after was one of the best I have had in awhile--it seems there is no predicting the arhythymias, but I feel they are definitely stress related. I also take some supplements which I feel help, being careful not to take too much. I hope you feel better soon.
