I really don’t think this is what happened to Damar. It mainly happens in pediatrics where the chest wall is not as developed as a grown man. It mainly happens when the object delivering the blow has a small surface area such as a baseball, there by concentrating the force of the blow. Damar had on shoulder pads which would have distributed the force over a large area of the chest. He had another arrest after having the heart restarted with an AED. That doesn’t happen with CC. I believe there was an underlying condition that caused the arrest.
