Abdominojugular test
Abdominojugular Test
The Abdominojugular Test (pronunciation: ab-dom-ino-ju-gu-lar test), also known as Hepatojugular Reflux or HJR, is a medical examination procedure used to assess right heart function and fluid status in patients.
Etymology
The term "Abdominojugular Test" is derived from the Latin words "abdomen" meaning belly, and "jugulum" meaning throat. This refers to the procedure's method of applying pressure to the abdomen and observing the jugular vein's response.
Procedure
The Abdominojugular Test is performed by applying pressure to the right upper quadrant of the patient's abdomen for 30 to 60 seconds while observing the jugular venous pressure. An increase in jugular venous pressure that lasts for more than 10 seconds after releasing the pressure is considered a positive Abdominojugular Test. This may indicate right heart failure or tricuspid regurgitation.
