Lancisi's sign

Lancisi's sign is a clinical sign in which a large venous wave, or Giant V wave, is visible in the jugular vein in patients with tricuspid regurgitation. It is caused by blood flowing backwards into the jugular vein through the incompetent tricuspid valve during ventricular systole.[1]

The sign is named after Giovanni Maria Lancisi.[2]
