Experimental Studies On Severe Blunt Cardiac Injury

Having maken the pendulum — like movement impactor system controlled by the cardiac cycle,we designed and taken a serial studies the following:part Ⅰ Effect of Impact Parameters on Primary Cardiac RuptureIn order to examine the effect of impact parameters on primary cardiac rupture,the exposed anterior ventricular surfaces of seventy — eight the open — chest rabbits were impacted directly with the impactor system.The experimental results were as follows: (1) The impacts at 5. 0 m/s resulted in no cardiac rupture (0/16) ;but the impacts at 8. 0 m/s resulted in...
