. Tricuspid regurgitation
There is normally an inspiratory decrease in the jugular venous pressure resulting from a reduction in intrathoracic and right-sided heart pressures. In conditions in which right-sided heart pressures are elevated and augmented right ventricular filling is limited, such as right ventricular infarction, constrictive pericarditis, or pulmonary embolism, the increased filling of the right-sided heart chambers that occurs with inspiration is transmitted into the jugular venous pulsation and elevation of the neck veins occurs with inspiration. With tricuspid regurgitation, a prominent V wave is observed but respiratory changes are not affected
