I get quite confused when people say AF will not kill you, my A F caused me to have a heart attack and could quite easily have killed me.
Being on anticoagulants does help but is not fool proof.
I have also heard of people suffering stroke also caused by AF that could also have killed them.
It's the life threatening things AF causes that's the danger.
I have had one unsuccessful ablation that was the most horrendous experience of my life and have just cancelled a second one preferring to trust the warfarin and biosprolol as and when.
