In medicine, Friedreich's sign is the exaggerated drop in diastolic central venous pressure seen in constrictive pericarditis (particularly with a stiff calcified pericardium) and manifested as abrupt collapse of the neck veins or marked descent of the central venous pressure waveform.

The sign is named after Nikolaus Friedreich.[1]
