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.

The invention relates to a correction method for correcting interference due to gradient injections in ECG signal data records recorded in a magnetic resonance device by an ECG measuring device. A first correction data record is determined with the ECG measuring device located in a first position. A second correction data record is determined by the ECG measuring device located in a second position. An ECG signal data record is measured by the ECG measuring device located in a defined position. A modified correction data record is defined as a function of the first correction data record and the second correction data record and the first and second position and the defined position of the ECG measuring device. The ECG signal data record is corrected based on the modified correction data record.

A method for monitoring a contacting of electrodes of an ECG measuring devices is provided. At least three signals each from a first and a second input signal are generated. The first and the second input signal emanate from different electrodes and each electrode supplies one of the input signals to at least two of the signals generated by a first signal processing unit. The three signals are compared with a reference value. Inadequately contacted electrodes are identified based on the comparisons and are displayed. A monitoring device for implementing the method is provided. The monitoring device comprises a first signal processing unit connected to the electrodes at an input side, a second signal processing unit for identifying the inadequately contacted electrodes by receiving and processing at least three signals generated by the first signal processing unit, and a display unit for displaying the inadequately contacted electrodes.

摘要:
The invention relates to a method for checking ECG signals measured by an ECG measuring device having at least three electrodes for the presence of interference errors. At least three voltages are measured on a closed circulation path across the electrodes of the ECG measuring device. A monitoring value is calculated from the three measured voltages. A presence of an error is checked by determining a deviation of the monitoring value from a reference value. An error signal is outputted if an error is presented. The ECG measuring device has a further processing unit for processing voltage signals between a different pair of electrodes and a monitoring unit for calculating the monitoring value.
