[Experiment study of the effect of enhanced external counterpulsation on shear stress]

This study inquired into the therapeutic mechanism of external counterpulsation(ECP) in the treatment of myocardial ischemia. Blood flow was measured at the arteria carotics, truncus brachiocephalics and other places in six chest-open dogs, and shear stress was operated. The statistical results show that the average, the range of change, and the changing rate were augmented with ECP, i.e. the phasic characteristics of shear stress were increased.
