Arrhythmia
"Have slow pulse plus atrial fibrillation-since newly diagnosed 2010 have been happy with results.Pulse beating much stronger and regular beat more frequently.  My husband takes for high blood pressure and atrial fibrillation and a much higher dose than I take.  He has been on it for a long time with excellent results.  Beta Blockers and other blood pressure pills did not seem to work for him.  All our bodies are different and respond to medication differently, but we are both satisfied."
