1. A system for assessment of mechanical variability of the heart, comprising:

  • a processing unit for receiving and storing scanned ultrasonic images, physiologic signals and a user-control input;

    ultrasonic means for providing said scanned ultrasonic images of the heart of a subject to said unit;

    a physiologic sensor for providing said physiologic signal of the subject for gating said scanned ultrasonic images so that said images are tagged by a specific time within the cardiac cycle with reference to a physiologic reference point when they are received by said unit;

    user means for providing said user-input for processing said gated ultrasonic image to achieve estimation of said variability of the mechanical activity of the heart; and

    display means coupled to said processing unit for receiving and displaying said variability of the mechanical activity of the heart.
