Estropipate
"I have been experiencing severe heart pounding and speeding due to menopause and not much has helped. I tried chinese herbs, bio identical hormones, birth control pill and beta blockers. My Endocrinologist put me on 3.0mg Estropipate and within a few days I'm experiencing more 'calmness' of the pounding. It's not completely gone but it has improved 90%, the good news is you can increase the dosage and it helps with bone density."
