De Musset's sign
De Musset's sign (pronunciation: deh moo-SETZ sign) is a clinical sign in medicine that is often associated with aortic insufficiency or aortic regurgitation. It is characterized by rhythmic nodding or bobbing of the head in time with the heartbeat.
Etymology
The sign is named after the French poet and novelist Alfred de Musset (1810-1857), who is believed to have suffered from the condition.
Clinical Presentation
Patients with De Musset's sign present with a noticeable nodding or bobbing of the head in synchrony with the heartbeat. This is due to the forceful ejection of blood from the left ventricle into the aorta, causing the head to move with each heartbeat. It is most commonly seen in patients with severe aortic regurgitation.
