3. “I take atenolol, a beta-blocker. Will it stop my A-Fib.”
Not usually. Beta-blockers like atenolol, in addition to calcium channel blockers, and digitalis compounds are all rate-control medications. They attempt to control your heart rate (ventricular beats), but leave your heart in A-Fib. “In fact, these (rate control) drugs, which are quite valuable in achieving ventricular rate control, have not been shown in placebo-controlled studies to restore sinus rhythm.”
However, we all react somewhat differently to meds. A drug that doesn’t work for one person may be very effective for another.
If you are under the impression that atenolol or other rate control drugs will stop your A-Fib, it might be wise to check with your doctor or get a second opinion.
