Louis Henri Vaquez

Louis Henri Vaquez (27 August 1860 – 15 April 1936) was a French internist born in Paris.

In 1890 he earned his medical doctorate, and in 1895 became médecin des hôpitaux in Paris.

Vaquez described the disease in a 40-year-old male suffering from chronic cyanosis, distended veins, vertigo, dyspnea, hepatosplenomegaly, palpitations and marked erythrocytosis.

[1] He was among the first physicians to recognize the correlation of Stokes-Adams attack to interference of the bundle of His causing a discordant beating of the atria in relation to that of the ventricles.

He is credited with introducing the electrocardiogram and recording of the jugular venous pulse into French medicine.
