| Abstract: | Correlation dimensionsD
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 CHD patient
can be identified byD
2 statistically andD
2 shows the potential application in the diagnosis of the CHD patients. |
