Avelox and heart problems

I was prescribed Avelox in March for a suspected minor sinus infection, after having already completed a 14-day course of Augmentin with no side effects. After 3 doses of Avelox I stopped because of these symptoms: fever to 100.5, tingling in feet, blood in urine, dizziness, faintness, vomiting, gastritis. A few days later I was diagnosed with atrial fibrillation (irregular heart rhythm), which I will now have to contend with for the rest of my life. Because I was formerly very healthy and had no heart problems, I am convinced the stress of the allergic reaction to Avelox caused the A fib. This drug should be avoided at all costs.
