Sustained elevation of JVP by more than 3 cm is considered a positive hepatojugular reflux. An elevation of 1 to 3 cm is considered normal.
What is hepatojugular 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. hepatojugular reflux.

Sustained elevation of JVP by more than 3 cm is considered a positive hepatojugular reflux. An elevation of 1 to 3 cm is considered normal.
What is the difference between hepatojugular reflux and positive abdominal compression?
The term "hepatojugular reflux" has been retained because it is so widely known that it is useful for indexing and referencing as well as for communication among physicians. However, the term positive abdominal compression test is preferable when describing the results of abdominal pressure.
What causes positive hepatojugular reflux in heart failure?
Constrictive pericarditis, right ventricular failure (commonly due to infarction), and restrictive cardiomyopathy are conditions that frequently produce a positive hepatojugular reflux. Left ventricular failure also produces this sign, but usually when the PCWP is more than 15 mmHg.

Does HJR stand for hepatojugular reflux?
The hepatojugular reflux (HJR) test was studied to assess the ability to clinically predict response during cardiac catheterization and to determine its significance in patients without heart failure and correlate it to their baseline hemodynamic parameters.
What is a normal JVP height?
The JVP is measured in centimetres vertically from the sternal angle to the top of the venous waveform. The normal upper limit is 4 cm. This is about 9 cm above the right atrium and corresponds to a pressure of 6 mmHg.
Is JVP increased in cirrhosis?
Fluid Thrill or Wave in Ascites Because cirrhosis is the most common cause of ascites, many patients with ascites demonstrate the stigmata of liver disease. An elevated JVP suggests a cardiac cause (e.g. heart failure, constrictive pericarditis) of ascites.
What causes raised JVP?
Causes of a raised JVP Right-sided heart failure: commonly caused by left-sided heart failure. Pulmonary hypertension is another cause of right-sided heart failure, often occurring due to chronic obstructive pulmonary disease or interstitial lung disease.
What is Hepatojugular?
The hepatojugular reflux, as presently defined, consists of a distention of the neck veins when pressure is applied over the liver. With a competent heart, pressure on the liver does not elevate the venous blood level in the neck veins when the subjects are in the semirecumbent position.
What causes neck vein distention?
JVD is a condition wherein increased blood pressure causes your jugular vein to bulge. Many cardiovascular conditions — including heart failure, high blood pressure, and fluid accumulation around the heart — can cause JVD.
How is JVP measured?
It has been taught that the best method for evaluating the JVP is to position the patient supine in bed, elevate the patient's head to approximately 30–45 degrees, and measure or estimate the vertical height of the meniscus of the right internal or external jugular vein above the sternal angle (angle of Louis) which is ...

What is hepatojugular reflux?
Hepatojugular reflux: Description, Causes and Risk Factors: 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 (CHF) and constrictive pericarditis by firm pressure with the flat hand over the abdomen often called hepatojugular reflux when pressure is exclusively over the liver.Causes and Risk Factors:Heart failure.
Why is hepatojugular reflux important?
Hepatojugular reflux can yield valuable information about cardiac function (especially of the right ventricle) and pulmonary function and is an important component of the assessment of volume status. The hepatojugular reflux is most commonly elevated with a raised venous pressure due to cardiac failure or hypervolaemia.In principle, the hepatojugular reflux reflects the height of the column of venous blood that rises above the physiologic zero point, which corresponds to the right atrium in humans. Symptoms: Symptoms may include:Getting tired very easily.

What is the abdominojugular test?
The abdominojugular test (AJR), also known as hepatojugular reflux or HJR is used as an alternate test for measuring jugular venous pressure (JVP) through the distension or swelling of the jugular vein.
What is a positive result in AJR?
Positive Result: A positive result is variously defined as either a sustained rise in the JVP of at least 4cm or more or a fall of 4 cm or more after the examiner releases pressure. The AJR has a reported sensitivity of 24% to 72% and a specificity of 96% to 93%. The large discrepancy in sensitivity may be explained by the higher value being reported during performance in optimal conditions of a cardiac lab while the lower value was from a study in an emergency room.
How long does it take for a doctor to press on the liver?

Is hepatojugular reflux a physical sign?
The hepatojugular reflux is a reliable but neglected physical sign which appears earlier in the course of congestive heart failure than the conventional signs and symptoms. In 1885, Pasteur originally described this sign as a manifestation of tricuspid regurgitation. However, experience has shown that it is present with heart failure of all etiologies.
How to perform the hepatojugular reflux test?

What is the most common cause of right sided heart failure?
dilated cardiomyopathy, end stage mitral valve disease) but pericardial disease typically fails to produce these more common clinical indicators of heart disease. Pericardial effusion is in fact the most common cause of right sided heart failure by creating cardiac tamponade, a process that refers to the collapse of the right atrium under the increased intra pericardial pressures created by pericardial fluid that dramatically compromises venous return to the heart leading to ascites.
How long after discharge is HJR checked?
All patients had detailed physical examination variables checked from the time of admission through 6 months after discharge. Among the physical examination variables is the HJR. We have included in this analysis all patients who had an assessment of the HJR on hospital discharge ( ). These cases were divided into two groups based on the presence or absence of a positive HJR. The primary study endpoints were all-cause mortality and a composite endpoint of death, rehospitalization, and cardiac transplant during the first 6 months after hospital discharge. We also aimed to find the determinants of a positive HJR and to evaluate the reliability of this clinical sign through studying its association with other clinical as well as objective hemodynamic variables of congestion measured by the PAC and echocardiography.
Is HJR a predictor of mortality?
The presence of a positive HJR on discharge of patients hospitalized with decompensated systolic HF correlates well with objective markers of volume overload and is an independent predictor of 6-month mortality. The HJR should be routinely checked in patients admitted with acute HF throughout hospitalization and especially on discharge as it serves as an important prognostic tool for postdischarge outcomes.
