Abnormal
Prolonged increase in JVP in patients with right or left ventricular failure, tricuspid regurgitation, increased pulmonary artery wedge pressure, central venous pressure.ab·dom·i·no·jug·u·lar re·flux (ăb-domi-nō-jŭgyū-lăr rēflŭks) A rise in jugular venous pressure of 1 cm or more that occurs during sustained pressure on the periumbilical area; associated with right-sided heart failure.
