Implication

May warrant ECG monitoring after blunt chest trauma without gross injury; hypothesis-generating in this canine model, requiring human validation.

PICO

Population

Experimental study on dogs subjected to blunt precordial impact to assess morphological and ultrastructural myocardial changes.

Intervention / Comparator

Blunt impact to the precordial region (8.0 m/s)

Primary Outcome

Morphological, ultrastructural, and immunohistochemical changes in the myocardium

Cite This Study

Guan et al. (1999) studied Cardiac concussion. Blunt impact to the precordial region was evaluated on Morphological, ultrastructural, and immunohistochemical changes in the myocardium. Experimental blunt precordial impact in dogs caused transient rhythm disorders, increased cardiac cell membrane permeability, and ultrastructural myocardial damage despite no gross injuries.
