摘要： An electromechanical system for generating a CPR-corrupted ECG signal is provided. The electromechanical system may include an ECG signal generator electrically coupled to a first contact of an AED. The electromechanical system may further include a potentiometer electrically coupled to the ECG signal generator and a second contact of the AED. The electromechanical system may further include a compression mechanism. The compression mechanism may be configured to receive a vertical force and adjust an impedance of the potentiometer according to the vertical force. The compression mechanism may include a rack having a plurality of teeth and an initial position. The rack may be configured to translate to a second position according to the vertical force. The compression mechanism may further include a gear with a plurality of teeth engaged with the teeth of the rack such that the gear rotates according to the translation of the rack.
