The Left Atrial Pressure Pulses in Experimental Mitral Valve Lesions

Abstract

Comparative studies of left atrial electrokymograms, left atrial pressure tracings, and pulmonary wedge pressure tracings were made in dogs with experimental mitral insufficiency or stenosis. Typical patterns were found in pure insufficiency or stenosis. A remarkable coincidence was found between pressure tracings and electrokymograms of the left atrium.
