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 flow. We concluded that IFM can be a useful tool to describe the physical heterogeneity of the ventricular muscle under the regional ischemia.
我们研究了使用阻抗频率曲线法（IFM）检测局部缺血的交叉循环分离犬左心室心肌物理异质性的可行性。在左前降支冠状动脉血流停止后，曲线从单峰形态变为双峰形态，随着左前降支冠状动脉血流再灌注，曲线又恢复为单峰形态。我们得出结论，IFM可作为描述局部缺血状态下心室肌物理异质性的有用工具。
