Differential diagnosisAortic insufficiency

It is named for French physician Paul Louis Duroziez who published its description in 1861,[3][4] even though it was first described by Portuguese physician Pedro Francisco da Costa Alvarenga in 1855;[5] for this reason it is alternatively known as the Alvarenga-Duroziez sign.
