Electrocardiographic signal transducer applied to a nuclear magnetic resonance tomograph

Abstract

Abstract 1. A device for obtaining an ECG-signal from a patient (8) who is arranged in a nuclear magnetic resonance tomograph (2) which is equipped with an HF-screen (2) which provides a protection from high-frequency irradiation, with a plurality of electrodes (18, 20, 22) which serve for connection to the patient (8) and to obtain an ECG-acquired signal, with an ECG-processing device (32) which forms the aforementioned ECG-signal (x, t) from the ECG-acquired signal, and with a connection cable (26, 30) which is arranged between the electrodes (18, 20, 22) and the ECG-processing device (32) and which comprises a cable screen (27, 34) characterised in that the cable screen (27, 34) is connected to the electrical potential of the HF-screen (12) and is not earthed to the ECG-processing device (32) itself.
