Electrokymographic Studies in Insufficiency of the Aortic and Pulmonic Valves

The following paper describes the results of electrokymographic studies performed on patients with proved aortic insufficiency. Alterations in the shape of the aortic ejection curve were found and were accompanied by a diminution or absence of the incisura in the presence of insufficiency of the aortic valves. Alterations in heart border motion of the ventricles were also found. The possible dynamic factors responsible for these changes are discussed and the clinical application of the electrokymograph to aortic and pulmonic valvular disease is pointed out.
