1. A system for monitoring a patient, comprising:

  • a sensor configured to be worn on the patient'"'"'s body, the sensor comprising an impedance sensor for measuring an impedance plethysmogram from the patient, an ECG sensor for measuring an ECG QRS complex from the patient, a motion sensor for measuring a motion signal from the patient, and a first wireless transceiver for transmitting information related to impedance, ECG, and motion signals;

    a first computer system configured to process;

    i) the impedance plethysmogram to determine a first fiducial value and a stroke volume value;

    ii) the ECG QRS complex to determine a second fiducial value;

    iii) the first and second fiducial values to determine a transit time value; and

    iv) the transit time to estimate a blood pressure value;

    a second computer system comprising a second wireless transceiver and a video output system, the second wireless transceiver configured to receive the motion signals, stroke volume value, and blood pressure value, or new parameters processed therefrom, and further process them to determine physiological and exercise information that is rendered through the video output system on a display.
