Abstract: The invention relates to an electrocardiogram arrangement having a plurality of lead channels, in which at least two lead channels are assigned an evaluation unit (1, 2, . . . ) which evaluates the ECG quality, classifies the results and locates the QRS complexes. For the QRS complex location, a central logic unit (14) selects that lead channel which has the highest ECG quality as the dominant lead channel. When special events occur in the dominant lead channel, other lead channels are accessed as appropriate.
Abstract: A defibrillator (1) having an integrated surveillance monitor (10), on the screen of which vital parameters of a patient can be displayed in the form of a rotatable screen content, having a built-in accumulator (9) for power supply independently of the main power supply and having a connection device (2, 3, 7) for external power supply and for recharging the accumulator (9). The screen content is rotatable from a first position relative to the housing to a second position relative to the housing in response to a change in position of the housing.
Abstract: The present invention relates to an apparatus for enhancing signals In ECGs including artefacts, said apparatus comprising a mean value unit (4) for evaluating from an ECG signal the curve shape of a predetermined number of beats from the beginning of a QRS complex to the end of a T wave and forming therefrom a mean value beat. A subtracting unit (3) subtracts the mean value beat from the ECG signal of an actual beat to thereby obtain a residual signal. A FIR filter unit (4) subjects the residual signal to high-low-pass filtering and delays it to provide a filtered signal to which the mean value beat is added in an adding unit.
Abstract: A defibrillator (1) including an integrated surveillance monitor (10) having a screen capable of displaying vital parameters of a patient, a built-in power supply device (9) for supplying power independently of an external power supply, and a connection device (2, 3, 7) for connecting the external power supply to the defibrillator where the screen content automatically rotates on the application of the external power supply.
