ECG Heartbeat Classification Based on an Improved ResNet-18 Model

Table 1

Mapping of the MIT-BIH heartbeat types to the AAMI heartbeat classes.

AAMI heartbeat classes	MIT-BIH heartbeat types
Normal (N)	Normal beat; Left bundle branch block beat; Right bundle branch block beat; Atrial escape beat; Nodal (junctional) escape beat
Ventricular ectopic (V)	Premature ventricular contraction; Ventricular escape beat
Supraventricular ectopic (S)	Atrial premature contraction; Aberrated atrial premature beat; Nodal (junctional) premature beat; Supraventricular premature beat
Fusion (F)	Fusion of nonectopic and ventricular beat
Unknown (Q)	Paced beat; Fusion of paced and normal beat; Unclassifiable beat
