Five to 10 minutes without a heartbeat — and without CPR — is enough to cause irreversible brain damage, he added. But even if a person is given good CPR, time still plays a role. For example, if it takes 30 minutes to get a heartbeat, the likelihood of being able to recover is “very slim,” Scheinerman said.

What type of heart attack kills instantly?

The most common life-threatening arrhythmia is ventricular fibrillation, which is an erratic, disorganized firing of impulses from the ventricles (the heart’s lower chambers). When this occurs, the heart is unable to pump blood and death will occur within minutes, if left untreated.

What happens when your heart stops for 20 minutes?

During cardiac arrest, unconsciousness will occur rapidly once the heart stops beating, typically within 20 seconds. Deprived of the oxygen and sugars it needs to function, the brain will be unable to deliver the electrical signals needed to sustain organ function, including breathing.

Can you survive if your heart stops for 20 minutes?

But it is not a final threshold. Doctors have long believed that if someone is without a heartbeat for longer than about 20 minutes, the brain usually suffers irreparable damage. But this can be avoided, Parnia says, with good quality CPR and careful post-resuscitation care.
