Hi,
Neck veins can provide valuable diagnostic information about your cardiopulmonary status. The right internal
jugular vein in particular is very important.
Jugular venous pressure reflects right ventricular filling pressure of the heart, and it remains the most reliable means of estimating central venous pressure or cardiac function. Are there other symptoms present? Distended neck veins could be due to cardiopulmonary causes such as heart failure, pericardial effusion, or pericarditis.
