Can you still breathe if your heart stops?
Blood continues to flow briefly in the brain and other organs, which can cause gasps for a few minutes after the heart stops. If cardiac arrest is the cause of agonal breathing, the labored breaths may only last a few minutes. Having had a heart attack makes it more likely to have cardiac arrest.
