Robust algorithm for arrhythmia classification in ECG using extreme learning machine

Table 1 Composition of the data set

Beat type	Number of beats in Test data set	Number of beats in Training data set	Possession rate (%)
Normal	54516	5000	70.2573
LBBB	6036	1000	7.7746
RBBB	5410	1000	6.9889
PVC	5293	1000	6.8166
APB	1896	1000	2.4407
PB	2702	1000	3.4853
Total	75853	10000	97.76

Possession rate means that possession ratio of each beat type in the entire MIT-BIH arrhythmia data base. LBBB: left bundle branch block, RBBB: right bundle branch block, PVC: premature ventricular contraction, APB: atrial premature beat, PB: paced beat
