What causes jugular venous reflux?
5 doctors weighed in across 2 answers
Physiology: The jugular vein connects directly to the superior vena cava and then to the right atrium of the heart. When the heart is overfilled, the jugular vein becomes distended. If you press on the liver, you can accentuate this ("hepato-jugular reflux") and that observation is used to increase the sensitivity of the physical exam for early signs of heart failure.
