The invention relates to an electrocardio-based fatigue prediction method and device and a storage medium, and is applied to the technical field of fatigue state detection, and the method comprises the steps: obtaining subjective and objective data of a fireman through simulating the training movement of the fireman, carrying out the clustering analysis of the subjective data, obtaining a grading threshold table under the optimal clustering number, and carrying out the calculation of the grading threshold table. The method comprises the following steps: performing weight analysis on subjective data to obtain the weight of each subjective feature, establishing a fatigue index F based on the weights of the subjective features, performing heart rate variability analysis on objective data to obtain a time domain, a frequency domain and a nonlinear index, establishing a model, taking the time domain, the frequency domain and the nonlinear index as the input of the model, and performing heart rate variability analy
