"It was a chilling sight for anyone who saw it," said Professor Stephan Achenbach, president of the European Society of Cardiology (ESC), the world's largest organization of heart doctors.

Christian Eriksen, a 29-year-old football player for Denmark, suddenly collapsed on the pitch in front of tens of thousands of spectators in the stadium and millions more watching on television. A medical team rushed to his side.

Preliminary reports suggest that while he was being treated on the pitch, Christian's heart stopped beating. He was exceptionally fortunate that there was a medical team to immediately begin chest compressions and maintain blood flow. It probably saved his life."

Eriksen is now awake in hospital. Doctors today confirmed that he suffered a cardiac arrest and was revived with an electrical shock.

Sudden cardiac arrest is a public health problem, accounting for 50% of cardiovascular deaths and 20% of all natural deaths in Western societies, according to a paper published in the European Heart Journal.

"Cardiac arrest can occur anytime, anywhere," said Prof. Achenbach. "The question is: Would you know how to respond? Every second is critical."

When to help:

– Someone is not breathing or only gasping for air;
– not otherwise moving or blinking;
– not responding, even to hard taps.

How to help:

– Push down on the center of the chest at a rate of 100 to 120 pushes a
minute. Allow the chest to come back up to its normal position after each
push;
– shout for someone to call an ambulance;
– ask bystanders to locate an AED (automated external defibrillator) and
follow the instructions.

"You can't do any harm by doing chest compressions" said Prof. Achenbach, "but you can save a life if the person is indeed in cardiac arrest."

Sudden cardiac arrest is such a public health threat that the ESC has made it the spotlight of its online scientific conference, ESC Congress 2021, which will be held at the end of August.
