Significant alterations in content of glycogen were observed during heart contraction. The maximal decrease (by 30.7%) in content of glycogen was found in preparations, obtained immediately after the R peak of electrocardiogramm. During the later steps of refractory period an increase in content of glycogen was observed and at the point, positioned 0.25 sec apart from the R peak, content of glycogen exceeded by 91.7% the initial level. | | Download PDF: | | Reference: Trubetskoĭ A.V., Lysenko L.T., Changes in the glycogen content of the dog myocardium at various phases of the cardiac cycle with a normal coronary blood flow, Voprosy meditsinskoi khimii, 1975, vol: 21(2), 158-161. | |
