I def would not leave USA 🇺🇸 w/o seeing any good EP Cardiologist ( stay in Mayo waitlist if you want ).
A-Fib is serious as you are at much higher risk of stroke ( and other serious complications). My sister was diagnosed in mid 50’s .
In all the meds for it . Then eventually had to get the ablation done . That helped a lot .
She still has her A fib meds but only half as many now .
Best wishes and n finding someone to help before you travel 🧭 for so long .
