Abstract
KOIWA, Y., HASHIGUCHI, R., OHYAMA, T., TAKAGI, T., KIKUCHI, J. and TAKISHIMA, T. The Instantaneous Impedance Frequency Curve of the Ventricle with the Regional Ischemia. Tohoku J. exp. Med., 1986, 149 (1), 103-104-We studied the feasibility of using the impedance frequency curve method (IFM) to detect the myocardial physical heterogeneity of a cross-circulated isolated canine left ventricle with regional ischemia. The curve changed from a single-peak configuration to a double-peak configuration after the LAD coronary flow cessation and returned to the single-peak configuration with the reperfusion of LAD coronary We concluded that IFM can be a useful tool to describe the physical heterogeneity of the ventricular muscle under the regional ischemia.
