The purpose of this research study is to use a test called impedance cardiography (ICG) to provide more information about how to improve the control of blood pressure. Participants will be given this test so investigators can get more information about what is going on inside the heart and blood vessels that is contributing to high blood pressure. ICG is a lot like an EKG (electrocardiogram) in that it uses electrodes and a computer to make a report. Participants will lie down on the exam table and two electrodes go on the right ankle and two electrodes go on the left wrist. The process takes about 5 minutes and is painless and not invasive.

The algorithm is configured to align medication choices based on the hemodynamic findings from the ICG readings. This decision support tool was created so as to organize these medications based on their mechanism of action and is consistent with the evidence-based treatment of hypertension.
The ICG system provides a printed report that indicates whether a person's hemodynamic state is predominantly one that is vasoconstricted, hyperdynamic, or mixed
