Diagram showing normal hepatic spectral Doppler waveform.
- A wave - atrial contraction causes retrograde flow back to liver, then rapid RV filling
- S wave - ventricular systole, antegrade flow into right atrium against closed TV
- V wave - opening of tricuspid, followed by rush of antegrade flow
- D wave - ventricular diastole, antegrade flow into RV
* RV = right ventricle, TV = tricuspid valve
