心外膜电图标测术已广泛用于改变心肌梗塞范围的研究,ST段抬高的幅度被认为是反映心肌缺血程度的一项指标。在研究梗塞后不同心肌区域的代谢特点时,一些学者也利用心外膜电图ST段变化情况作为划分各个梗塞区的依据。然而,关于犬急性梗塞期心外膜电图ST段改变区域分布的详尽资料是不多的。现将我们的初步观察结果报告如下。
Epicardial electrocardiography has been widely used to change the scope of myocardial infarction study, ST segment elevation is considered to reflect the extent of myocardial ischemia an indicator. In studying the metabolic characteristics of different myocardial regions after infarction, some scholars also use the changes of epicardial ST segment as the basis for dividing each infarct. However, there is not much information on the regional distribution of ST segment changes in acute infarction epilepsy. Now our preliminary observations are reported below.
