频谱心电图(FCG)是利用生物控制论及信息处理的方法来分析心电信号。我们在不同程度冠脉狭窄犬上观察FCG有何变化。我们用微米狭窄器造成冠状动脉左旋支(LCX)轻、中、重度三种狭窄情况,同步记录冠脉血流量(CBF)、动脉压、左心室压,收缩时间间期、导纳阻抗微分图、
Spectrum electrocardiography (FCG) is the use of biological control theory and information processing methods to analyze ECG signals. We observed varying degrees of coronary stenosis dog FCG changes. We used micro-stenosis device to make three kinds of stenosis of light, moderate and severe left circumflex coronary artery (LCX), and simultaneously recorded coronary blood flow (CBF), arterial pressure, left ventricular pressure, systolic time interval, admittance impedance differential graph ,
