Hepatic vein Doppler waveform components I VExUS I POCUS

In this short video, we talk about how the hepatic vein Doppler waveform is generated. Hepatic vein Doppler is an important component of VExUS, or Venous Excess Ultrasound, and understanding the individual waveforms is essential for accurate interpretation. As we'll see, each component of the waveform reflects specific events occurring in the right atrium and right ventricle throughout the cardiac cycle. Whenever possible, it's also helpful to record a simultaneous ECG. Correlating the Doppler tracing with the ECG makes it much easier to identify the individual waveforms and their abnormalities.
