摘要:
The frequency analysis of the electrocardiogram reveals that contributions by frequencies of 100 cycles, or higher, per second are less than 10 per cent of the amplitude of the fundamental of the QRS comples, and it thus appears that transistor-driven amplifier-pen recorders presently available are adequate to record all the information contained in the electrocardiogram, if the standard paper speed is doubled, or quadrupled.
