Riesman's Sign
Riesman's Sign (/ˈriːzmən/; from the German surname Riesman, meaning "giant man") is a clinical sign in medicine that is used to diagnose certain cardiovascular conditions. It is named after the German physician David Riesman, who first described it in the early 20th century.
Definition
Riesman's Sign is a clinical sign observed in patients with aortic insufficiency, a condition where the aortic valve does not close tightly, allowing some blood to leak back into the left ventricle. The sign is characterized by a pulsation of the uvula that is synchronous with the heartbeat.
Clinical Significance
The presence of Riesman's Sign can be an important diagnostic clue in patients with suspected aortic insufficiency. However, it is not always present in patients with this condition, and its absence does not rule out aortic insufficiency. Other clinical signs and symptoms, as well as diagnostic tests such as an echocardiogram, are typically needed to confirm the diagnosis.
