A method of obtaining an electrocardiograph (ECG) of a patient located in a turbulent electromagnetic environment. The method includes recovering an ECG signal from a patient. The signal, including added noise, is recovered near the cardiac region as the differential signal resulting from signals delivered by two electrodes forming part of a first measurement loop. The signal further consists of simultaneously recovering from the patient a second measurement signal incorporating at least the noise, as a differential signal resulting from the signals delivered by two electrodes forming part of a second measurement loop distinct from the first measurement loop. Then, the second measurement signal is added or subtracted from the first noisy ECG signal, in real time. The second measurement signal is as a function of the polarity of the noise in the second signal relative to the noise in the first noisy ECG signal. The resulting signal is processed, converted, transmitted and displayed in real time representing the ECG essentially devoid of noise.
A method of obtaining the electrocardiograph (ECG) of a patient located in a turbulent electromagnetic environment, consisting of recovering an ECG signal from the patient with added noise near the cardiac region as the differential signal resulting from the signals delivered by two electrodes forming part of a first measurement loop, characterized in that it further consists of simultaneously recovering from the patient (1) in essentially identical turbulent conditions, a second measurement signal (S2) incorporating at least the noise, as a differential signal resulting from the signals delivered by two electrodes (5, 5′) forming part of a second measurement loop (4) distinct from the first (2), then adding to or subtracting from the first noisy ECG signal (S1), in real time, said second measurement signal (S2) as a function of the polarity of the noise in said second signal relative to the noise in the noisy ECG signal (S1) and, finally, processing, converting, transmitting and/or displaying in real time the resulting signal (SR) representing the ECG, which is essentially devoid of noise.
