<s>[INST] Am 70 yr old male, fit with good diet. Diagnosed with paroxysmal AF which has been present possibly as long as seven years now. Does it get reclassified as chronic AF by the passage of time? I take Flecainide 200mg per day which I read is not recommended for chronic AF. A brain scan shows multiple small embolic infarcts presumably from before I started on the Flecainide and (for 18 months) Warfarin. Should I press my doctor to be assessed for electrical ablation? The AF does not affect normal living, and I know the operation carries risk, but the brain scan scares me. [/INST] Hello, I will suggest you continue with flecainide and anticoagulants. Electrical ablation is recommended only when your routine drugs are not working the way they should be or you do develop some unwanted side effects of these medications (if still, it does reclassify as chronic A.fib). Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Dr Muhammad Faisal Bacha, Internal Medicine Specialist </s>
