Commotio cordis is a rare type of blunt cardiac injury in which low impact chest 
trauma causes sudden cardiac arrest, usually occurs from being struck by a 
projectile during sports. The most common arrhythmia during commotio cordis is 
ventricular fibrillation, although complete heart block and an idioventricular 
rhythm have also been reported. We describe a case of a young patient who 
presented with a persistent third-degree atrioventricular block and a left 
bundle branch block, following blunt chest trauma, as a result of blow by soccer 
ball and subsequently needed a permanent pacemaker.
