Embodiment Construction
[0060] The components in the figures are not necessarily to scale relative to each other, like reference numerals refer to corresponding parts throughout the several views.
[0061] figure 1 is a diagram of a system for non-invasively determining arterial flow characteristics in the heart using wide-band cardiac gradient data, according to an exemplary embodiment. like figure 1 As shown, the system 100 includes a broadband biopotential measurement device 102 and an analysis subsystem 104 . Broadband biopotential measurement device 102 acquires broadband biopotentials from subject or patient 110 via at least one electrode 106 (shown as surface electrodes 106a, 106b, . . . , 106n ) and corresponding common mode reference leads 108 Signals 112 (shown as 112a, . . . , n) (also referred to herein as broadband cardiac gradient signal data 112), the at least one electrode 106 and the corresponding common mode reference lead 108 are both in figure 1 and are attached to the surface ...
