Carl Nothnagel
From Wikipedia, the free encyclopedia
Carl Wilhelm Hermann Nothnagel (September 28, 1841 - July 7, 1905) was a German internist, who is credited with describing in 1876 the irregular pulse associated with atrial fibrillation, which he called "delirium cordis".
From 1858 - 1863, Nothnagel studied under Ludwig Traube (1818-1876) and Rudolf Virchow (1821-1902) at the Friedrich Wilhelms-Institut in Berlin. After receiving his doctorate, part of his early career was spent as a military physician, including a stint in the Franco-Prussian War. From 1882 - 1905, he was a professor at the university clinic in Vienna.
Two eponyms that are associated with Nothnagel:
- Nothnagel's syndrome I: a rare condition characterised by pallor, blanching of the skin and narrowing of the blood vessels after being exposed to cold conditions.
- Nothnagel's syndrome II: oculomotor palsy and cerebellar ataxia caused by a lesion affecting the oculomotor nucleus and cerebellar peduncles (stalk-like band of neurons).
