1. A method for assessing a physiological signal quality based on an Intra-Aortic Balloon counterPulsation (IABP) device, comprising:
acquiring, in an operation process of the IABP device, a physiological signal of a patient treated by the IABP device, wherein the physiological signal comprises an electrocardiographic signal and/or an arterial blood pressure signal;
extracting signal parameter values of the physiological signal;
wherein the signal parameter values comprise: a first kurtosis, a skewness, an effective signal ratio, a second kurtosis, and a dominant frequency, the first kurtosis represents a steepness or a flatness of the physiological signal in a time domain distribution, the skewness represents a direction and a degree of deflection of the physiological signal in the time domain distribution, the effective signal ratio represents a ratio of an effective component relative to a total component in the physiological signal, the second kurtosis represents a steepness or a flatness of the physiological signal in a frequency domain distribution, and the dominant frequency represents a frequency corresponding to the second kurtosis of the physiological signal in the frequency domain distribution;
performing signal quality assessment on the physiological signal based on the signal parameter values;
in response to a signal quality assessment result represents that a signal quality of the physiological signal satisfies a preset signal quality requirement, implementing intra-aortic balloon counterpulsation based on the physiological signal.
