Abstract
Electrokymographic tracings of left auricular pulsations in normal and diseased states are described. A characteristic abnormality observed in persons with organic mitral valve insufficiency is believed to be graphic evidence of regurgitation of blood from ventricle into atrium. Electrokymographic evidence of regurgitation was found in persons with mitral stenosis without an audible systolic murmur but instances of mitral stenosis without insufficiency were recorded. Patients with Austin Flint murmurs and individuals with murmurs mimicking mitral insufficiency showed uniformly normal atrial pulsations.
