    • In a defibrillator with an electrocardiographic monitor which monitors electrocardiographic signals induced at electrodes by means of a preamplifier and supplying the signals to an electrocardiographic signal processing circuit through high-pass filters, the dynamic range of a preamplifier is made wider in accordance with the amplitude of a polarization voltage which is developed when a defibrillator is operated. A high-pass filter is formed of a first high-pass filter which operates in a normal state and a second high-pass filter whose blocking frequency is higher than that of the first high-pass filter so that the polarization voltage is attenuated without erasing the electrocardiographic signals. The second high-pass filter is operated in synchronization with the operation of the defibrillator during a time period corresponding to the time period in which the polarization voltage is generated.
