I am a 54 year old male with an enlarged heart due to genetics. Here lately it has been going a-fib a lot more often, and staying longer. I was taken to the hospital with Congestive Heart Failure last Monday. It is May, and my ablation surgery isn't until August at the earliest. I am taking amiodarone, lisinopril (zestril), metoprolol (lopressor), and am on warfarin (coumadin) bloodthinners. I have been coughing a lot with the CHF, which causes me to go into and out of A-fib. Is there anything I can do to get back into sinus rhythm?
