abdominojugular reflux(redirected from abdominal ugular reflux)
an elevation of venous pressure visible in the jugular veins and measurable in the veins of the arm, produced in active or impending congestive heart failure and constrictive pericarditis by firm pressure with the flat hand over the abdomen. Often called hepatojugular reflux when pressure is exclusively over the liver.
Synonym(s): abdominojugular reflux
abdominojugular refluxAn increase in jugular venous pressure which follows 10–30 seconds of pressure on the periumbilical region, which is due to an increased inflow of blood from the abdominal veins into the right atrium.
Transient rise of ≤ 3 cm H2O in JVP.
Prolonged increase in JVP in patients with right or left ventricular failure, tricuspid regurgitation, increased pulmonary artery wedge pressure, central venous pressure.
