Embodiments include an electrocardiography system that includes or is connected to a sensor arrangement, wherein the sensor arrangement includes surface electrodes that record electric signals. The electrocardiography system includes a signal processing unit, with filters and amplifiers, which is electrically connected to the sensor arrangement. The electrocardiography system includes a signal evaluation unit connected via a first signal input to the signal processing unit. The signal evaluation unit processes one or more prepared ECG signals provided by the signal processing unit in order to recover an electrocardiogram signal and to display the electrocardiogram signal. The signal evaluation unit includes a second signal input that receives secondary signals obtained by body sensors or monitors, wherein the signal evaluation unit processes the prepared ECG signals depending on the secondary signals.
