Jugular venous pressure is used to estimate pressures in which chamber?

Explanation:
Jugular venous pressure is a direct reflection of the right atrial filling pressure. The systemic venous return flows into the right atrium, and there are no valves between the jugular veins and the atrium, so changes in RA pressure are transmitted up to the external jugular column. Measuring how high the venous pulsation rises above the sternum (at the level of the sternal angle) gives an estimate of the right atrial pressure, essentially the central venous pressure. The left-sided chambers (left atrium and left ventricle) aren’t determined by JVP, and while right ventricular pressures relate to right-sided heart dynamics, JVP most directly indicates RA pressure.
