A system and method for evaluating cardiovascular performance in real time and characterized by conversion of a surface potential into multi-channels are introduced. The system includes an electrocardiographic signal measuring unit, a reconstruction unit, and a parameter computation and assessment unit. The reconstruction unit reconstructs electrocardiographic signals (ECG signals) recorded by the electrocardiographic signal measuring unit, such that the ECG signals are reconstructed as ones located at different spatial positions but actually not having a channel. The method includes calculating a variation manifested spatially during an interval between a Q wave and a T wave of an ECG signal against time with a parameter computation and assessment algorithm, to evaluate its discreteness degree and thereby diagnose cardiovascular diseases (CVD) and locate lesions thereof.

The present invention relates to a method for analyzing bio-signal instantaneously by Chaotic Phase Space Difference (CPSD) operation and its measure analyze device. This method includes time-delay procedure and rebuilt phase space matrix to calculate complexity of phase space matrix and diagnose the bio-signal. This method can also be used as an analyze method in portable device or 24 h ECG recorder which is a fast and convenient measure analyze device.
