(Redirected from Commotio Cordis)
- Sudden cardiac arrest resulting from blunt chest trauma in absence of underlying cardiac disease
- 50% of cases due to competitive sports
- Baseball is most common culprit
- Autopsy usually shows normal cardiac anatomy with no evidence of damage to heart or other intrathoracic structures
- Primary electrical event resulting in induction of Ventricular Fibrillation
- Likely due to blow occurring 10-30ms before peak of T wave, although this theory is disputed
- Strike directly over cardiac silhouette ↑ risk of developing commotio cordis
- Younger patients more at risk - compliant chest wall allows transmission of more energy to the heart.
- Cardiac arrest (usually ventricular fibrillation)
- Standard adult or pediatric cardiac arrest management
- Prognosis is poor, with only 16% survival rate
- Admit to ICU if ROSC is achieved
- See Post Cardiac Arrest
