Heart and I’m new here

I have tachycardia and bradycardia with afib but over the last two months when I tried to do things I sweat like nothing and it also affects my breathing I’m not sure I like this but I’m wondering whether it is the medication causing it as I did get a phone call to say my heart is going 107 50% of the time as I take 2.5mg of bisoprolol and on edoxaban 60mg know we are before I was only taking 1.25mg
