The left atrium is situated in a way where it receives oxygenated blood sent from the lungs to be pumped into the left ventricle, passing the mitral valve, which.Too many signs referred to left atrial enlargement are in fact due to the delayed interatrial conduction velocity (that is interatrial block). In sinus rhythm the right atrial depolarization wave (brown) precedes that of the left atrium (blue) and the combined depolarization waves, the P wave, is less than 120 ms wide and less than 2.5 mm high. In right atrial abnormality, right atrial.
