The safety for the Buffalo Bills, 24-year-old Damar Hamlin, was in critical condition in the ICU at a Cincinnati hospital on Tuesday. The Bills said he went into cardiac arrest after colliding with another player during Monday night's game against the Bengals. As prayers come in from across the nation to Hamlin and his family, doctors here in Seattle shared how something like this can happen. Doctor Jordan Prutkin with the University of Washington Medicine Heart Institute said cardiac arrest is not a heart attack, it is an electrical issue that causes a life-threatening fast heartbeat. “So that is presumably what happened yesterday, is that something caused his heart rhythm to go super-fast and he needed to be shocked to get out of it,” said Dr. Prutkin.  Prutkin said this could have been caused by many different things. One possibility being discussed is Commotio Cordis, because Hamlin collapsed seconds after taking a hit in the chest. “What that is, is when there's a sharp or a high force object that hits the center of the chest, and if there's a certain time window in the electrical signal of the heart, when that object hits the chest, it can cause a cardiac arrest,” said Prutkin.
