Experimental Analytical Study on Electrocardiogram(VII) : III. Relationship bevrteen mono- and polyphasic e, c. g. : The effect of tissue membrane impedance to the action current : 2. Experimental proof, especially, on phase difference between initial complexes of mono- and polyphasic e. c. g.

Abstract

Mono- and polyphasic e. c. g. were recorded by unipolar lead on the same point of frog's heart. These curves coincide with theoretical curves which are traced by equation (3) & (12). In the initial complexes of these 2 kinds of curves, phase difference is found. Namely, the time when monophasic e. c. g, become maximal value (q-deflection), coincide with the time when polyphasic e. c. g. pass the zero line. Experimental results, above mentioned, is concluded as follow. Action current of excitable tissue itself is represented as nionophasic, but by rnembran impedance it is deformed to polyphasic. This is the view of " Theory of chaine-doublet" (Maekawa).
