Major features selected by stepwise discriminant analysis.

Major features
T wave type, Down-T-slo_p90, Up-R-slo_p75, P-amp_p10, Up-T-slo_p90, RR-int_p95, QRS-amp_p1, T-int_p99, QRS-amp_p75, Down-R-slo_p99, Down-R-slo_p95

Note: “-int” represents the length of the indicated interval, “-slo” represents the slope of the indicated waveform, and “-amp” represents the amplitude of the indicated wave.
