Taken to hospital

Following the incident, Eriksen was transported to hospital, where he underwent further examinations to determine the cause of the collapse.
Internal defibrillator believed to have helped

It is believed that the implanted cardioverter-defibrillator Eriksen received after suffering cardiac arrest in 2021 played an important role during the incident.

What an ICD does

An implantable cardioverter-defibrillator (ICD) is a battery-powered device placed beneath the skin.
It monitors the heart's rhythm and can deliver electrical shocks if it detects dangerous rhythm disturbances.
Team doctor praised the device's performance

Denmark national team doctor Morten Boesen stated that the internal defibrillator responded as intended and that Eriksen was able to walk off the pitch on his own.
Defibrillators can restore heart rhythm

A defibrillator analyses the heart's rhythm and can deliver electrical shocks to help restore a normal heartbeat.

Found in many public places

Defibrillators are not only used by people with heart conditions. They can also be found in workplaces, schools, gyms, and other public locations.
Rapid response is critical

Defibrillators are most effective when used within minutes of a cardiac arrest. For that reason, acting quickly is essential.
Can be used without medical training

These devices are designed so that people without a medical background can use them in emergencies by following the built-in instructions.
How to use a defibrillator

If a person is unconscious and not breathing normally, emergency services should be called immediately while cardiopulmonary resuscitation (CPR) is started.

The defibrillator should then be switched on and its instructions followed.
Four possible warning signs before cardiac arrest

Some people experience symptoms before the heart stops pumping blood.
These warning signs may include chest discomfort, shortness of breath, weakness, and heart palpitations.
Cardiac arrest and heart attack are not the same

During a heart attack, a person is often conscious and breathing.

In a cardiac arrest, the person typically collapses suddenly, becomes unconscious, and stops breathing normally.
Certain heart conditions increase the risk

Some forms of heart disease can increase the risk of sudden cardiac arrest.
The most common cause is a serious heart rhythm disturbance known as ventricular fibrillation.
