High Blood Pressure
"Started this medication over a year ago, and it has helped keep my heartbeat regular.  I had an episode where my heart rate was over 200bpm, and had to go to the ER in an ambulance from my doctor&#039;s office.  It has not repeated, thank goodness, and I had no side effects from this medication, which I take with Zestril (which I&#039;d been taking for many years before)."
