    摘要： A differential voltage measuring system includes two electrodes that are connected to a patient at an input and make available a respective measurement contact at an output. A shunt resistor is connected in series with the second electrode. A first amplifier circuit has a first input for a first signal from the first electrode, a second input for a second signal from the second electrode, and an output. A second amplifier circuit has a first input that is connected in series with the shunt resistor, a second input that is connected in parallel with the shunt resistor, and an output. A first signal detection unit is provided at the output of the first amplifier circuit, and a second signal detection unit is provided at the output of the second amplifier circuit. The second signal detection unit detects the signal from the second amplifier circuit as a measurement variable.

    摘要： An electrode for producing electrical contact with skin is provided. The electrode includes a first electrical connection, a second electrical connection that is electrically insulated from the first electrical connection, and a skin contact. The skin contact has a first contact region that is electrically coupled to the first electrical connection, and a second contact region that is electrically insulated from the first contact region and is electrically coupled to the second electrical connection. The skin contact is configured to produce electrical contact between the skin and the skin contact when the electrode is in a state placed on the skin.

    摘要： Methods, noise detection devices, and differential voltage measuring systems are provided for detecting noise signals for the purpose of measuring cardiac movements in a patient. In the method, contact is made with the patient by at least two measuring electrodes having at least one associated measuring channel. Furthermore, a heartbeat measurement is performed. During the heartbeat measurement, signals from the patient are detected over the at least one measuring channel. Then, a check is made of whether the detected signals have been caused by noise by comparing the detected signals with at least one heartbeat type that was identified in the course of the learning procedure.

    摘要： A differential voltage measuring system is described. The differential voltage measuring system has a signal measuring circuit for measuring bioelectric signals, and an interference-signal measuring circuit coupled to the potential of the differential voltage measuring system and electrically connected to a fixed reference potential. In this case, the interference-signal measuring circuit is designed for measuring a current flowing from the potential of the differential voltage measuring system to the fixed reference potential. A differential voltage measuring system with an additional path is also described. Furthermore, a differential voltage measuring system with an averaging potential measuring method is described.
