A description is given of the longitudinal elasticity of the heart as a whole by introducing the longitudinal average length of the cardiomyocytes and calculating the change in the longitudinal average length of the cardiomyocytes from the capacitance. A continuous, high-sampling-rate, non-invasive method is provided to measure the motion of myocardial tissue at the whole cell level, thereby enabling the detection of more subtle abnormal changes in the myocardial cells.)
