Abstract
An electronic system is disclosed which examines the first derivative of an applied electrocardiographic (ECG) signal, recognizes the R-wave event therefrom, and discriminates against signal components which lie outside predetermined signal parameters in producing a rectangular pulse output. In addition, muscle artifact and pacers are discriminated against. The system includes an automatic gain control to eliminate the need for operator controls.
