Abstract :
Performance measures to compare QRS detection algorithms are suggested and evaluated. The measures are used to compare various linear and nonlinear filters and to determine optimal threshold levels. In low error cases the separation divergence is suggested as a performance measure. For single lead systems this measure becomes an F-ratio measure. A database of more than 2700 complexes is used. With this database several types of linear filters and nonlinear operators are compared and optimal threshold levels are determined
