Abdominojugular Reflux: Sensitivity and Specificity
Introduction: Compression of the right upper quadrant while observing the JVP. A positive, abnormal, result occurs when the JVP remains elevated throughout the compression. This has been found to correlate with an elevated pulmonary capillary wedge pressure (as in congestive heart failure), possibly resulting from increased total blood volume (PMID 3415106).
