I am a believer that resting calmer heart is wise.
But this just happened with my brother age 80 and me age 76. We are both on Eliquis and both have intermittent Afib. I have had an ablation and take no heart or BP drugs. My brother takes a number of drugs. My brother also works out almost everyday even if he has a cold or recovering from a bad virus which I believe is very unwise. But that said
last week we both went out of Afib within 2 days of each other. I took the rest is better approach and my brother hammered it with 4 mile walks and some weight lifting.
I self converted to sinus after 18 hours of Afib. And my brother self converted to sinus 30 hours of Afib. So what is the correct approach? I do not think the 12 hour difference is proof that my approach is best. In fact a few times when I have been in Afib for a few days and might take a quick fast walk and find that I return to sinus within a couple of hours.
