THE ESTABLISHMENT OF EXPERIMENTAL ANIMAL MODEL OF CARDIAC CONTUSION / 中国法医学杂志

ABSTRACT

In the present study an experimental animal model of closed chest cardiac contusion in dogs was successfully established by impacting precardial area at the velocity of 9- 1 - 10. 5m/s with home-made elastic cord propelled impactor, After impact, some significant abnormalities of the left and right ventricular pressure,ECG and heart rate were recorded. Cardiac contusions were demonstrated at au-topsy. The establishment of the experimental cardiac contusion model could provide the tool for further study on nonpenetrating cardiac injury.
