Dual Gate Doppler

First-class cardiac display and analysis

The Dual Gate Doppler generates a full FFT analysis and display from two separate sample gates allowing measurements from two different locations, during the same cardiac cycle. For example:

  • PW/PW:
    • LV inflow and PV flow - for pseudonormalisation assessment
  • PW/TDI:
    • E-wave, A-wave and e'- E/e', as a way of evaluating diastolic dysfunction
  • TDI/TDI:
    • septal wall TDI and lateral TDI - evaluation of cardiac resynchronisation therapy
