Among them, 20 patients were candidates of valve replacement and 18 PDA and pericarditis had their blood samples taken before operation,and 1,2,24 and 48 hours after closure of thorax for measurement of concentrations of CK、CK-MB and TnT,together with ECG recording. Results Of the 60 patients, concentrations of cTnT before operation were normal; 2 hours after aortic unclamping, the correlation coefficient between cTnT and aortic clamping was r = 0.873( P＜0.01), the regression analysis showed Y = 0. 019X-0. 026. Of the 20 patients, ECG showed the myocardium was ischemic; CK、CK-MB and cTnT all rose significantly, reaching the peak after closure of thorax. Of the 18 patients, the ECG and cTnT before operation and after closure of thorax were normal; except 2 patients with pericarditis.

Finally, FastICA in time domain is derived based on instantaneous BSS system, and convolutional mixture BSS algorithm in frequency domain is obtained based on convolutional mixture BSS in time domain. Then we combine the two algorithms together and present the complex-value FastICA algorithm in frequency domain, which is a new BSS technique. We merge preprocessing in time domain and correlation coefficient solution in time domain into this new algorithm and present Time-Frequency domain FastICA BSS System.
