Figure 10. Beat-level MAPE distributions of the conventional rule-based method under different auxiliary information conditions. (A and B) correspond to ECG-only and ECG + PCG-assisted, respectively. Each method is evaluated on n = 92 valid test beats. Each dot represents an individual beat; the width of the half violin indicates the kernel density distribution of MAPE values, the horizontal line represents the median, and the diamond indicates the mean.
