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.
正在考虑两种保护心电图仪输入级联免受除颤器脉冲影响的典型方案。得出的结论是，国家标准R 50267.25（MEK 601-2-25-93）中设想的检查和测试条件与实际运行条件不符，因此建议对上述标准进行适当修改。所提供的方案显示可确保电极极化电位降低100倍。
