Cardiovascular injury from blunt thoracic impact of Epinephrine and Isoproterenol injected rabbits.

Nonpenetrating thoracic impact of 10 anaesthetised rabbits injected with Epinephrine and experiencing transient hypertension resulted in 4 incidents of traumatic rupture of the left ventriculair injury. The experiments indicate that the precondition of the myocardium is an important factor in the incidence of ventricular and major vascular rupture in nonpenetrating thoracic impact.
