About

The purpose of this study is to determine the effect of slowing heart rate upon both central and peripheral blood pressures using a medication called Ivabradine which slows heart rate without affecting heart contraction, and to compare the effects of ivabradine to a traditional blood pressure lowering medication called metoprolol (which is a beta-blocker).
