Thanks for your reply. You may guess I am in fact an Aussie. Bushwalking is mostly walking on formed tracks in our National Parks
with a bit of rock hopping here & there. and
yes, I am on that wretched warfarin
, however my INR level is kept around 2.5. The maker of my mechanical valve (ONX) state they are investigating if an INR of 2.0 might be sufficient. Your Afib sounds similar to a friend of mine. He is amazing the way he copes with it.
