The more clinically relevant blood pressure (BP) at the heart differs significantly from BP at the upper arm. BP at the heart can only be measured directly through an invasive procedure. This patent provides a simple and non-invasive method of estimating BP at the heart from a non-invasive pulse recording on the wrist.
