Study shows: One in five patients who can be resuscitated has a near-death experience. Around 65,000 people in Germany suffer a sudden cardiac arrest every year.

In around 60,000 of them it is fatal, according to the German Society for Cardiology – Heart and Circulation Research (DGK) Every minute in which a person is not treated with chest compressions after a cardiac arrest, the probability of survival decreases by 10 percent, the DGK says. Anyone who masters chest compression greatly increases a heart patient's chances of survival in an emergency.
