Measurement station with electrocardiogram measurement

A measurement station comprising:

• an electrocardiogram (ECG) acquisition system,
• two control electrodes configured to contact a user,
• an electrical connection circuit, the electrical connection circuit comprising a feedback loop connected to each of the two control electrodes,
• an impedance measurement system,
• wherein:
• (i) the ECG acquisition system comprises:
• a plurality of ECG electrodes configured to contact a user's body,
• an ECG electronic circuit connected to the plurality of ECG electrodes, and wherein the two control electrodes are distinct from the plurality of ECG electrodes such that neither of the two control electrodes is used by the ECG acquisition system to collect ECG signals,
• (ii) the impedance measurement system comprises:
• a current source,
• two current injection electrodes adapted to inject a current into a user's body, and wherein the current source is connected to the electrical connection circuit and the two current injection electrodes are the two control electrodes, and
• (iii) the electrical connection circuit is electrically independent of the ECG electronic circuit.
