What caused Damar Hamlin's cardiac arrest?

It's unclear what caused Hamlin's cardiac arrest. As an NFL player, he regularly exercises and eats healthy meals, so it is unlikely to have been caused by some of the common risk factors such as high cholesterol or high blood pressure. 

What is commotio cordis? 

It's possible Hamlin suffered a condition known as "commotio cordis," which is an injury associated with blunt-force trauma to the heart. Although infrequent, it can cause sudden cardiac arrest in young athletes. According to the National Library for Medicine, the condition is usually caused by a hard strike during physical activity. 

The condition only happens during a rare set of circumstances: when a sharp hit lands directly over the heart β€œat the exact wrong location at the exact wrong timing” during the heart’s rhythm cycle, said Dr. Rod Passman, director of the center for arrythmia research at Northwestern University’s Feinberg School of Medicine.
