high blood pressure
"This medication does keep my hypertension under control and also seems to effect my heart rate by lowering it by an average of 15--20 bpm. I  take other medications that tend to raise my heart rate, so this medication is useful for me, in that regard. I have found that this medication is very sensitive to dosing propery. I have found that if I miss only a couple of doses, my blood pressure and heart rate start to increase."
