Commotio Cordis and Damar Hamlin

The video discusses the incident involving Damar Hamlin, who collapsed during a game due to a chest impact. This led to a cardiac arrest, possibly caused by Commotio Cordis, a condition where the heart is disrupted by a specific type of chest impact. The video explains the precise conditions needed for this to occur, including the timing and force of the impact. Fortunately, medical staff responded quickly, and Hamlin is now recovering.

• During the recovery phase

• During the resting phase

• During the relaxation phase

• During the contraction phase

What percentage of the heart's cycle is vulnerable to Commotio Cordis?

• 10-15%

• 5-10%

• 20-25%

• 1-2%

What is crucial about the force of the impact in Commotio Cordis?

• It must be applied continuously
