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
