New here, but hoping for some help... Recently had a long bout of a-fib so severe was hospitalized with shortness of breath and heartrate near 200. Was put on Metoprolol (beta-blocker) and Xarelto (anticoag), and heartrate still was high, so beta-blocker was doubled to 100mg day (50 am, 50 pm). After about a month, had the cardioversion procedure, which stabilized heartrate. Beta-blocker reduced to 50 mg a day. About a month later, had Echo-cardio test and things had "returned to normal." Because of bad side-effects from Metoprolol, doctor weaned me off it and said I could replace baby aspirin for the Xarelto. After several days (4 or 5) was back into A-fib. Doc said go back on original meds (50mg BB & 20mg Xarelto). Got A-fib under control, but the bad side-effects were overwhelming, so doc put me on CCB Diltiazem instead of beta-blocker, 30mg 3 x day.
Now am having what feels like "rebound a-fib" when the dosage tends to wear off. (Tend to wake in early morn with heart racing, irregular beat; this never happened with the beta blocker.) Also having bad side-effects from the CCB, including digestion problems and dizziness and brain-fog. Any ideas how I can control the A-Fib without all these bad side-effects? Am tempted to dump the Diltiazem and go back to low dose of beta-blocker and hope the nasty side-effects won't be so severe with only 25 mg/day. Feeling like a guinea-pig with an out-of-control heart at this point.
Also, is it OK to take 1/2 - 1 mg of Lorazepam during an A-fib episode? It seems to help slow down the racing.
Any suggestions/advice very welcome. Thanks!
