What kind of side effects is she having? I lasted on atenolol a whole 4 days and then told me doctor she had to find something else. I was only getting a few hours of sleep a night, plus is made me feel asthmatic and had episodes of Raynaud's syndrome as mentioned above. Since I live in Iowa (low of -24 degrees the other day), it was a side effects that really bothered me. Now I am on 240 mg of Diltiazem and no side effects but it is not controlling the rapid pulse rate very well. My husband, who has A-fib, saw a mention on one of the discussion boards he reads of Beta Blockers lowering the levels of Melatonin in some patients and causing sleep disturbances.
Hi,
What about trying propranolol (inderal)

I use it for mitral valve arrhythias (fibrillation) to reduce rate though I have a minor side effect (Raynaud's disease). or Lowpressor http://blood-pressure.emedtv.com/lopressor/lowpressor.html

Do you have blue fingers, LBBB, atrial enlargement or other?
