It is unclear what caused Hamlin’s cardiac arrest. As an NFL player, he exercises regularly and eats healthy, so it’s unlikely that it was caused by some common risk factors like high cholesterol or high blood pressure.

Hamlin may have suffered from a condition known as “commotio cordis”, which is a blunt force trauma to the heart. Although uncommon, it can cause sudden cardiac arrest in young athletes. According to the National Library of Medicine, this condition is usually caused by a strong blow during physical activity.

The condition only occurs in a rare set of circumstances: when a sharp blow hits the heart “in the completely wrong place at the completely wrong time” during a heart rate cycle, said Dr. Rod Passman, director of the arrhythmia center. research at Northwestern University’s Feinberg School of Medicine.
