The difference between cardiac arrest and a heart attack Buffalo Bills safety Damar Hamlin, 24,
suffered a cardiac arrest and collapsed on the field during the first quarter of Monday night’s game between the Bills and Cincinnati Bengals, his team said. It’s not clear what caused his cardiac arrest.
Cardiac arrest results from electrical disturbances that cause the heart to suddenly stop beating properly.
In cardiac arrest, death can result quickly if steps aren’t taken immediately. “Cardiac arrest may be reversed if CPR is performed and a defibrillator shocks the heart and restores a normal heart rhythm within a few minutes,” according to the American Heart Association.
More than 350,000 cardiac arrests occur outside a hospital in the United States each year, the AHA said.
A sudden, unexpected loss of heart function also results in a sudden loss of breathing and consciousness.
Cardiac arrest is not the same as a heart attack, although almost any known heart condition, including heart attack, can cause cardiac arrest.
Unlike cardiac arrest, a
heart attack is a circulation problem. When circulation is blocked or cut off in some way and blood is no longer supplied to the heart muscle, this can damage that muscle – it’s commonly described as a heart attack; doctors may refer to it as “myocardial infarction.”
