Abstract
The impedance cardiography device comprises an impedance measuring unit, connected to the human body to be measured, a differentiator, a comparator and a microcontroller integrated with an analog-to-digital converter, characterized by that the device further comprises two peak voltage detection units with different polarities (positive and negative), the strobing outputs of them being connected to the digital (binary) inputs of the microcontroller and the analog hold outputs to the inputs of the analog-to-digital converter.
