Every year, more than 350,000 people have a cardiac arrest outside of a hospital. Few survive. While many people who have been resuscitated have no memories of the experience, a recent study suggests others recall something, whether it’s a vague sense that people are around them, or more specific dreamlike awareness.
Unlike a heart attack where people are awake and the heart is still painfully beating, those in cardiac arrest are always unconscious. They have no heartbeat or pulse and need CPR urgently. In essence, they have “flat-lined” and are so near death there is no activity on electronic monitors.
What a near-death experience is has never really been defined. Researchers have been trying to explore what’s happening when a patient’s heart stops to see if there are themes or patterns of consciousness.
“There is an assumption that because people do not respond to us physically, in other words, when they’re in a coma, that they’re not conscious, and that’s fundamentally flawed," said Dr. Sam Parnia, a pulmonary and critical care specialist at NYU Langone Health, and the lead author of the recent study.

To find out more about the experiences of the few survivors who have a sense of consciousness during heart-related near-death events, NBC News connected with participants in the NYU Langone research and others from the Cardiac Arrest Survivor Alliance online community, a program of the Sudden Cardiac Arrest Foundation, and the Near-Death Experience Research Foundation.
They shared what they saw, heard and felt during resuscitation, how their lives changed afterward and what they believe other people should know about death and dying.
