1. A non-invasive cardiac monitoring system comprising:

  • a photoemitter adapted to transmit light through a portion of a patient'"'"'s extra-thoracic arterial circulation;

    a photodetector adapted to receive light after having been transmitted through such a patient and for outputting a first signal based on the received light;

    processing means for producing a cardiac pressure signal as a measure of such a patient'"'"'s cardiac function by isolating cardiac related pressure variations in the first signal.
