Distribution of AAMI heartbeat classes in the two independent datasets

Dataset	N	S (SVEB)	V (VEB)	F	Q	Total
DS1	45868	942	3787	415	8	51020
DS2	44258	1837	3221	388	7	49711

The MIT-BIH arrhythmia database was divided into two datasets as described in [1]. N, S (SVEB), V (VEB), F and Q refer to heartbeats originating in the sinus node, supraventricular ectopic beat, ventricular ectopic beat, fusion heartbeat, and unknown beat type, respectively. Four recordings (102, 104, 107 and 217) containing paced beats were not included. Dataset DS1 includes data from recording 101, 106, 108, 109, 112, 114, 115, 116, 118, 119, 122, 124, 201, 203, 205, 207, 208, 209, 215, 220, 223 and 220. Dataset DS2 includes data from recording 100, 103, 105, 111, 105, 7, 11, 121, 123, 200, 202, 210, 212, 213, 214, 219, 221, 222, 228, 231, 233 and 234.
