Abstract
A pulse amplifier and ratemeter for measuring heart rate are described. The self-biasing arrangement which is used in the amplifier greatly reduces the effects of changes in the mean level, shape, amplitude and duty cycle of the pulse. The ratemeter has rapid response and is suitable for continuous recording.Keywords
