Phasic Analysis of Cardiac Cycle on the Basis of Polygraphic Tracing Apex Cardiogram, Phonocardiogram and Carotid Tracing

摘要

(1) By the use of polygraphic tracing including apex cardiogram, phonocardiogram and indirect carotid tracing, an almost full and precise phasic analysis of the cardiac cycle may be obtained. (2) New methods for the measurement of the ejection period and mechanical systole are presented.
