Commotio cordis, or heart concussion, is sudden death from blunt chest trauma. This case study details a baseball injury survivor, suggesting coronary vasospasm may contribute to this condition.

Area of Science:

  • Cardiology
  • Sports Medicine
  • Trauma Research

Background:

  • Commotio cordis is a rare cause of sudden cardiac death following blunt chest trauma.
  • It is hypothesized to result from ventricular fibrillation triggered by chest impact during the heart's vulnerable repolarization phase.

Observation:

  • A case of commotio cordis caused by a baseball impact is presented.
  • The patient experienced documented ventricular fibrillation, successfully treated with defibrillation.
  • Serial electrocardiograms revealed bifascicular conduction block and T wave inversion.

Findings:

  • The patient survived commotio cordis following a baseball injury.
  • Ventricular fibrillation was the initial cardiac event, responsive to defibrillation.
  • Electrocardiographic changes indicated myocardial injury and conduction abnormalities.

Implications:

  • This case highlights the potential for survival from commotio cordis with prompt medical intervention.
  • The findings suggest that coronary vasospasm may be a contributing factor in commotio cordis.
  • Further research into the mechanisms and management of commotio cordis is warranted.
