Right internal jugular vein remains preferred for JVP assessment given direct anatomical communication with right atrium.
Demonstrates the anatomical alignment of the right internal jugular vein, indicating why it serves as the preferred anatomical conduit for evaluating right atrial pressure.
Jugular venous pulse is defined as the oscillating top of vertical column of blood in the right Internal Jugular Vein (IJV) that reflects the pressure changes in the right atrium in cardiac cycle.In other words, Jugular venous pressure (JVP) is the vertical height of oscillating column of blood (Fig 1).Fig 1: Schematic diagram of JVP NECK VEIN OF CHOICE FOR JVP MEASUREMENT Right internal jugular neck vein should be used to test the JVP because the right internal jugular vein communicates directly with the right atrium via the superior vena cava.Even though there is a functional valve at the junction of the internal jugular vein and the superior vena cava, usually, this valve does not impede the phasic flow of blood to the right atrium.Thus the wave form generated by phasic flow to the right atrium is accurately reflected in the internal jugular vein.The relatively direct line between the right external and internal jugular veins, as compared to the left external and internal jugular veins, make the right jugular vein the preferred system for assessing the venous pressure and pulse contour.

Maddury Jyotsna (2017) reported a review. Right internal jugular vein JVP assessment vs. Left jugular vein JVP assessment was evaluated. The right internal jugular vein is the preferred site for assessing jugular venous pressure due to its direct anatomical communication with the right atrium via the superior vena cava.
