What does a heart starter do?
A heart starter, also known as an implantable cardioverter defibrillator (ICD), is a small device that regulates abnormal heart rhythms.
Thin wires connect the device, placed under the skin just below the collar bone, to the heart and monitor your heart rate through electrodes.
The device is similar to a pacemaker but used to restart the heart if it goes into a rhythm that cannot ensure contraction of the ventricle.
What has been said?
A statement by the Danish FA read: “National team doctor Morten Boesen has been in contact with the cardiac specialist at Rigshospitalet and Christian Eriksen and this is the latest status.
“‘After Christian has been through different heart examinations it has been decided that he should have an ICD (heart starter). This device is necessary after a cardiac attack due to rhythm disturbances.
“Christian has accepted the solution and the plan has moreover been confirmed by specialists nationally and internationally who all recommend the same treatment.
“We encourage everybody to give Christian and his family peace and privacy the following time.’”
What happened to Eriksen?
Eriksen went down in the 43rd minute of the Euro 2020 match between Denmark and Finland. It quickly became clear the situation was serious and the game was suspended for over 90 minutes while the 29-year-old was assessed and treated.
After being treated by medics on the pitch, Eriksen was then transferred to a Copenhagen hospital where he was “stabilised”. The match was then cleared to resume.
Having been goalless before the stoppage, the game finished 1-0 to Finland with Joel Pohjanpalo heading home to give the Fins their first win at a major tournament on their debut.
On Sunday, the Danish FA confirmed that the Inter Milan player was awake and had spoken to his team-mates.
Denmark face Belgium at 5pm (BST) in their second group-stage game.
Romelu Lukaku announced Belgium will put the ball out of play in the 10th minute in the game as a tribute to his Inter Milan team-mate.
