Ventricular Precontracting Area in the Wolff-Parkinson-White Syndrome

Abstract

By means of the analytic method of roentgenkymography of Cignolini, 11 typical cases of Wolff-Parkinson-White syndrome were studied. Comparison of the kymographic tracings with the synchronously registered electrocardiogram demonstrated precocious contraction of a limited ventricular area, situated in the left ventricle in the A type and in the right ventricle in the B type.
