Overview

The cardiac atria are the two upper chambers of the heart, the right atrium and the left atrium, which receive blood returning to the heart and pass it to the ventricles below. The right atrium receives deoxygenated blood from the body through the venae cavae, while the left atrium receives oxygenated blood from the lungs via the pulmonary veins. The atria contribute to ventricular filling, and their walls house key elements of the heart's electrical conduction system, including the sinoatrial node, which initiates the heartbeat. Atrial structure and electrical activity are clinically important because disorders such as atrial fibrillation, atrial tachycardia, and atrial enlargement affect rhythm, cardiac output, and the risk of thromboembolism, and chronic conditions such as hypertension can alter atrial structure and function over time. Hypertension and Cardiology covers cardiovascular disease and its assessment, including work relevant to atrial electrophysiology, such as a technique to estimate the origins of focal atrial tachycardias from 12-lead electrocardiograms and a case report of Ebstein's anomaly with right atrial thrombus. This page gathers peer-reviewed, open-access research relevant to the cardiac atria and their role in cardiovascular health and disease.
