ECG-Based Multiclass Arrhythmia Classification Using Beat-Level Fusion Network

Figure 3

The heartbeat-level weights assigned by the proposed interbeat feature fusion module for different ECG classes including (a) myocardial Infarction, (b) conduction disturbance and myocardial infarction, (c) myocardial infarction and ST/T change, and (d) conduction disturbance and hypertrophy and myocardial Infarction. The upper subfigures in (a)–(d) show the original ECG signal from lead II. The lower subfigures show the corresponding heartbeat-level weights.
