Lancisi's sign
Lancisi's sign
Lancisi's sign (pronounced lan-see-zees sign), also known as jugular venous pulse or JVP, is a clinical sign in medicine. It is named after the Italian physician Giovanni Maria Lancisi, who first described it in the 18th century.
Etymology
The term "Lancisi's sign" is derived from the name of its discoverer, Giovanni Maria Lancisi (1654–1720), an Italian physician and epidemiologist. Lancisi was a pioneer in the study of malaria and heart disease, and he was the first to describe the sign that now bears his name.
Definition
Lancisi's sign is a visible and palpable double pulsation in the jugular veins, particularly noticeable when the patient is in a semi-recumbent position. It is often associated with severe right-sided heart failure and tricuspid valve disease.
Related Terms
- Jugular venous pressure: The indirectly observed pressure over the venous system via visualization of the internal jugular vein.
- Heart failure: A chronic condition in which the heart doesn't pump blood as well as it should.
- Tricuspid valve disease: A type of valvular heart disease that affects the tricuspid valve, one of the four valves in the heart.
Clinical Significance
Lancisi's sign is a valuable diagnostic tool in cardiology. It can indicate the presence of severe right-sided heart failure or tricuspid valve disease. However, it is not specific for these conditions and can be seen in other diseases such as pulmonary hypertension and constrictive pericarditis.
