Multi-channel real-time cardiovascular performance evaluation system and method cardiovascular performance evaluation system and method

A multi-channel real-time cardiovascular performance evaluation method, adapted to construct a multi-channel real-time cardiovascular performance evaluation system, the system comprising:

• a multi-channel ECG signal measurement unit, used to detect and measure ECG signals for different spatial positions of a heart, wherein the ECG signals have P waves, Q waves, R waves, S waves, and T waves;
• a multi-channel ECG signal processing device, connected to the multi-channel ECG signal measurement unit, and to input the ECG signals that are measured into an internal circuit of the device, for reconstructing the ECG signals that are measured;
• and
• an ECG signal reconstruction unit, disposed on the internal circuit of the multi-channel ECG signal processing device, an electrocardiogram (ECG) extracted wave reconstruction module being stored in the ECG signal reconstruction unit, that is referred to an MAMA-EMD firmware,
• the multi-channel real-time cardiovascular performance evaluation method comprising steps of:
• step 1:
• adding a masking signal to the ECG signals, to filter out high frequency noises;
• step 2:
• determining and marking a first characteristic peak point of the ECG signals with the masking signal;
• step 3:
• utilizing an MAMA-EMD de-peak function to smooth out the ECG signals, in order to replace the first characteristic peak point of the ECG signals with the masking signal;
• step 4:
• performing waveform comparisons with results obtained in the step 2 and step 3, in order to remove baseline drift from the ECG signals with the masking signal, and obtain a first signal having the first characteristic peak point;
• step 5:
• determining and marking the results of the waveform comparisons in the step 4, to extract a second characteristic peak point of remaining signals filtered by the MAMA-EDA firmware;
• step 6:
• utilizing the MAMA-EMD de-peak function to smooth out the ECG signals to replace the second characteristic peak point of the remaining signals;
• and
• step 7:
• performing waveform comparisons with results obtained in the step 5 and step 6, to remove baseline drift from the remaining signals, and to obtain a second signal having the second characteristic peak point;
• wherein through utilizing separate time points of the first signal of a reconstructed QRS wave, the second signal of the T waves, the start of the Q waves, and the end of the T waves, the multi-channel real-time cardiovascular performance evaluation system determined whether there is a cardiovascular disease;
• wherein the MAMA-EMD reconstruction firmware used for reconstructing the ECG signals is realized in a hardware circuit.
