摘要： A system for monitoring a patient includes a first drive electrode configured to be in contact with the patient. The first drive electrode is configured to receive a first electrical current and inject it into the patient. The system also includes a first sense electrode configured to be in contact with the patient. The first sense electrode is configured to sense a first bio-electric signal from the patient. The first bio-electric signal is modified by the first electrical current. The system also includes an impedance circuit connected to the first drive electrode and the first sense electrode. The impedance circuit is configured to measure a bio-impedance or bio-reactance waveform in response to the first bio-electric signal. The system also includes a physiological sensor connected to the first drive electrode and the first sense electrode. The physiological sensor is configured to measure an electrocardiogram waveform based upon the first bio-electric signal.
