Title: Response of the canine heart to thoracic impact during ventricular diastole and systole
Abstract: This experiment was performed to determine if cardiac injury, as a consequence of thoracic impact, is related to the contractile state of the myocardium at the time of impact. Twenty-six male dogs (20–25 kg) were anesthetized and impacted at various times in their cardiac cycles using a vertical impact generator. The results indicate that ventricular injury is dependent (in part) on the contractile state of the ventricular myocardium at impact. In all cases of ventricular rupture, the myocardium was in the high pressure phase of the cardiac cycle (i.e., systole). Neither right nor left ventricle showed gross pathology if impact occurred during the low pressure phase of the cardiac cycle (i.e., diastole).
