Emergency Medical Minute Podcast 843: Commotio Cordis
Contributor: Jared Scott, MD
Educational Pearls:
- Commotio cordis is sudden ventricular fibrillation precipitated by direct impact to the chest
- A national registry, US Commotio Cordis Registry, reports an average of 10-20 cases annually
- 95% of reported cases occur in males, indicating possible genetic component
- Average age of patient in registry is 15
- Most cases occur during sporting events (baseball in particular), in addition to physical altercations and industrial accidents
- Treatment is high quality CPR and early defibrillation
- Survival rate is improving but remains around 35%
- In recent events, American football player Damar Hamlin survived a Commotio cordis event after being tackled on field and receiving CPR
