摘要：
Correlation dimensions D-2 of the synchronous 12-lead ECG signals have been investigated for the first time by distributed multi-sensor (multi-electrode) technique. The results show that correlation dimension of heart has the distributed characteristics. D-2 calculated from different lead ECG signals is not a constant regardless of a healthy person or a coronary heart disease (CHD) patient with sinus rhythm. But with the same lead signal, D-2 of CHD patients is evidently smaller than that of a healthy person except I, II, III leads. A healthy person and GHD patient can be identified by D-2 statistically and D-2 shows the potential application in the diagnosis of the CHD patients.
