arrhythmia
"In persistent Atrial Fibrillation for 11 months being switched around between various doses and combinations of metoprolol and diltiazem for rate control without success.  Converted on second dose of Tikosyn and had absolutely no problems with dosing in hospital other than a little headache on first dose.  I never knew how bad I felt in Atrial Fibrillation until normal sinus rhythm restored.  Check with your doctor about this medicine.  They have a great program to insure safety medicine loading (although three days in the hospital CAN get a little boring!)."
