In a method for enhancing the signal-to-noise ratio of ECG signals, A/D-converted signals from a plurality of cardiac cycles are time-synchronized to form a signal ensemble, whereupon the concordance between the signals in the ensemble is determined in time intervals, comprising at least two samples, during at least a part of the cardiac cycles. A device for enhancing the signal-to-noise ratio of ECG-signals, comprises means (4, 5) for recording, A/D-converting and other processing of the ECG-signals. A synchronization unit is arranged to time-synchronize the signals from a plurality of cardiac cycles to form a signal ensemble, and a calculator unit (12) controlled by a window unit is arranged to determine the concordance between the signals in the ensemble in time intervals, comprising at least two samples, during at least a part of the cardiac cycles. <IMAGE> |
