<s>[INST] my husband is having artial fib and he is wearing a holter monitor, but he only has episodes at night, never during the day, only at rest, he is exhausted, already suffers from low blood pressure, we re frustrated with our Cardiologist approach. He is 70 6 and generally healthy [/INST] For atrial fibrillation, very good treatment is available. Your cardiologist should focus, first on rate control which can be achieved with beta blockers like metoprolol, diltiazem or if blood pressure is low even if not having any episodes then tab digoxin or amiodarone.

Second important thing is anticoagulation which keeping blood thin otherwise it may lead formation of clot in heart and this clot may dislodge leading to stroke or paralysis. So discuss both these issues.Also, during the episodes take rest and lye Down. </s>
