Abstract
Displayed ECG waveforms are maintained within acceptable aspect ratios without rapid fluctuation in amplitude by rapidly decreasing the gain of the signal channel by discrete amounts as the peak-to-peak amplitude of the ECG signal increases through each of a number of levels and by increasing the gain of the signal channel only after the peak-to-peak amplitude of the ECG signals has dropped to a given fraction for a predetermined period of time.
