Intermittent left bundle branch block (LBBB) as a clinical manifestation of myocardial contusion after blunt chest trauma.
Injury to the heart in blunt chest trauma is dependent on a number of factors. Symptoms are often non-specific, and there is no gold standard test for diagnosis. Injuries to small areas of the myocardium may only be identified at autopsy. We report a 38 year old man who sustained a number of injuries in a road traffic accident, and in whom the single clinical or ECG abnormality was a left bundle branch block (LBBB); he had a myocardial injury rated as grade II. The patient was treated for his injuries and later discharged. As this is a difficult diagnosis, algorithms of blunt chest trauma may save time and money by avoiding misleading diagnosis and unnecessary monitoring and admissions.
