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.
