Ecg system and method for the large-surface measurement of ecg signals
First Claim
1. An ECG system for large-surface recording of ECG signals, characterized by a first measuring means (10) for generating a first measured data record including at least one reading of the cardiac currents, at least one lead site of the first measuring means (10) being variable during the recording of the large-surface ECG signals, a second measuring means (20) for simultaneously generating a second measured data record including at least one reading of the cardiac currents, the lead site of the second measuring means (20) being spatially invariable during the recording of the large-surface ECG signals in order to obtain continuous measurement results, and a data processing system (30) having a means for synchronizing at least two signals, determined in a temporally offset fashion, of the first measured data record with at least one continuously detected signal of the second measured data record.

Abstract
The invention relates to an ECG system for the large-surface measurement of ECG signals which is characterized by a first measuring device (10) for generating a first set of readings comprising at least one derivation of the electrical impulses of the heart. At least one site of derivation of the first measuring device (10) during recording of the large-surface ECG signals is variable. The system further comprises a second measuring device (20) for generating a second set of readings comprising at least one derivation of the electrical impulses of the heart. The site of derivation of the second measuring device (20) during recording of the large-surface ECG signals is spatially invariable in order to obtain continuous readings. A data processing system (30) is provided with means for synchronizing at least two signals of the first set of readings that are detected at different times with at least one continuously detected signal of the second set of readings. The inventive system allows for the large-surface detection of ECG signals and for their efficient use in everyday hospital routine.
