TABLE 3. Sensitivity of QRS Detection on the MITDB With Respect to Different Types of Abnormal Beat Morphologies.

Beat type	VEB^a	PVC^b	SVEB^c	PAC^d	LBBB^e
Se (%)	99.44	99.43	99.67	99.91	99.96

^{^a}

See Fig. 6 for a definition of all included beat types in this category.

^{^b}

Premature Ventricular Contractions (indicated by “V” in the MITDB reference annotations). This is a subtype of the VEB category.

^{^c}

See Fig. 6 for a definition of all included beat types in this category.

^{^d}

Premature Atrial Contractions (indicated by “A” in the MITDB reference annotations). This is a subtype of the SVEB category.

^{^e}

Left Bundle Branch Block (indicated by “L” in the MITDB reference annotations). These beats are not included in the SVEB or VEB categories.
