Thanks for your reply rubyw. Sorry to hear your afib is so often! My Dr also has discussed ablation if attacks continue.
You say "I strongly urge you to take your questions and concerns to your cardiologist…..the ONLY person who can give you the answers you are obviously desperately searching for." I respectfully disagree… Of course we need to have these type discussions with our cardiologist (and I have), but we also can research it on our own. Unfortunately most Dr.s after 20-30 years of doing the same rote thing over and over get in a rut like anyone else. They have their developed opinions based on facts but a lot of this is still opinions by a single Dr then. For instance, if you ask 10 cardiologists how long Xarelto takes to get to max strength in your blood after initial dose, I bet 9 will not know – they just don't NEED to know such details. They KNOW from experience and training that taking the blood thinner reduces the chances of a clot forming from our Afib and that is enough. Nothing against them, but they too are human.
As an engineer, I like to research things myself, understand how they work. Especially when it affects me and no one else seems to have the data. I now learned Xarelto takes only 2 hours to become very effective. For instance, how long does it take for a dangerous blood clot to form during Afib? Seems to me there should be a typical known (from imperical tests) time: IF that time is > 2 hours, then my taking Xarelto 24/7 is a waste and doing more harm than good to my body since I can tell when I go into Afib once every month or so (so far).
This is why I am still searching for the answer to that open question. If the answer is a blood clot can form in first 3 minutes of Afib attack, then so be it – gotta take Zarelto 24/7 to cover that one bout next month or the month after. If it takes 3 hours, I will discuss it with my cardiologist and determine if he can agree with my assessment to stop taking it until needed. Obviously this is not an option for anyone who cannot tell right away when they go into Afib.
