ABSTRACT
The dynamic changes of synchronous 12-lead ECG signal's correlation dimension (D2) of an anesthetized rabbit were investigated primarily under three different pathologic conditions. The results showed that the D2 derived from different lead signals was not a constant whether the rabbit was in normal state or in emergent myocardial infarction condition, it demonstrated distribution characteristic. Compared with the same lead signal, D2 of limb lead almost kept constant, D2 of chest lead got higher when the sphere of emergent ischemia extended larger. D2 showed the potential application in the diagnosis of coronary heart disease.
