Definition

The pressure within the CARDIAC ATRIUM. It can be measured directly by using a pressure catheter (see HEART CATHETERIZATION). It can be also estimated using various imaging techniques or other pressure readings such as PULMONARY CAPILLARY WEDGE PRESSURE (an estimate of left atrial pressure) and CENTRAL VENOUS PRESSURE (an estimate of right atrial pressure).

Common questions about Atrial Pressure

What does Atrial Pressure mean in medicine?
The pressure within the CARDIAC ATRIUM. It can be measured directly by using a pressure catheter (see HEART CATHETERIZATION). It can be also estimated using various imaging techniques or other pressure readings such as PULMONARY CAPILLARY WEDGE PRESSURE (an estimate of left atrial pressure) and CENTRAL VENOUS PRESSURE (an estimate of right atrial pressure). This definition is taken from the National Library of Medicine's MeSH (Medical Subject Headings) 2026 release, which is the standard vocabulary used to index PubMed and most medical literature.
Is Atrial Pressure known by any other names?
Yes. Atrial Pressure is also referred to as Atrial Pressures, Pressure, Atrial, Pressures, Atrial, Intra-atrial Pressure in different clinical, research and patient-facing contexts. The MeSH descriptor groups all of these synonyms under a single canonical concept so research and records stay consistent.
Where does Atrial Pressure sit in the medical classification?
Atrial Pressure falls under the broader medical category "Phenomena and Processes" in the MeSH hierarchy (tree numbers: G09.330.040.600, G09.330.380.037). Browsing the related concepts on this page takes you to neighbouring topics in the same branch of medicine.
