    摘要： The method is related to control a measurement of a magnetic resonance device based on electrocardiogram signals of a patient detected by at least two channels. The method comprises the steps of: supplying the electrocardiogram signals in a first processing branch to a low pass filter and a derived value sum generator; comparing the output signal with a threshold value to generate a first comparison result; feeding the electrocardiogram signals in a second processing branch to a derived value generator; comparing said signals with an upper and a lower threshold value to generate a second comparison result; repeat the above steps for the second and if necessary further channels; evaluating all first and second comparison results for all channels in a weighted logic circuit; and triggering the measurement as a function of the result of the weighted logic circuit.

    摘要： Method for ECG triggering a measuring sequence of a magnetic resonance device, with ECG signals of a patient being detected over two channels, with the triggering of the measuring sequence being carried out when the ECG signal of at least one channel, said ECG signal being subjected to a digital signal processing, exceeds a threshold value, and at the same time the derivation of the ECG signal or the norm of the derivation of the ECG signal lies within a defined interval in both channels.

    摘要： The invention relates to a correction method for correction of noise resulting from gradient artifacts in ECG signal data records recorded in a magnetic resonance device by an ECG measuring apparatus. A first correction data record is determined with a reference point of the ECG measuring apparatus located at a first position in the magnetic resonance device. An ECG signal data record is measured with the reference point of the ECG measuring apparatus located at a second position in the magnetic resonance device. A modified correction data record is specified as a function of the first correction data record and the first and second position of the reference point. The ECG signal data record is corrected based on the modified correction data record.
