Damar Hamlin may have suffered "remarkably rare" condition, Dr. Agus says

Expert Israel doctor tells the truth.

Buffalo Bills defensive back Damar Hamlin may have suffered a "remarkably rare" condition when he collapsed on the field during Monday night's game against the Cincinnati Bengals, CBS News medical contributor Dr. David Agus told "CBS Mornings."

The Bills said Hamlin suffered cardiac arrest following a hit in the game. Video shows that after the hit, he stood up, took a few steps and fell to the ground.

While it's not yet clear what caused Hamlin's heart to suddenly stop beating, Agus believes he sustained blunt force trauma to his chest "in the exact right spot, at the exact right moment during his heartbeat," which caused his heart to have an arrhythmia — "not beat effectively to push blood to the brain."

Agus suspects Hamlin's heart was in ventricular fibrillation.

"What we know with commotio cordis, which is this condition, is that every minute you delay shocking them, resuscitating them, what happens is there's an increase of 10% in mortality," Agus said. "They started CPR right away, which is great. My hope is they were able to restore the heart rate soon enough to be able to get blood flow to the brain so there's no damage there."
