[A comparison of the two schemes of protection of the electrocardiograph against defibrillator impulse].
Two typical scheme of protection of the input cascade of the electrocardiograph against defibrillator impulses are under consideration. It is concluded that the conditions of check-up and testing as envisaged in State Standard R 50267.25 (MEK 601-2-25-93), is not in line with the real operation conditions, therefore, appropriate changes are suggested to be made in the above Standard. The offered scheme is shown to ensure a decrease of the electrodes' polarization potential by 100 times.
