Denmark’s Christian Eriksen will be fitted with a heart-starting device following his collapse on the pitch during Euro 2020.

The 29-year-old midfielder suffered cardiac arrest in his side’s defeat by Finland in Copenhagen on Saturday.

The ICD – implantable cardioverter defibrillator – is “necessary due to rhythm disturbances”, Danish team doctor Morten Boesen said.

Eriksen remains in hospital but says he is “fine under the circumstances”.

The British Heart Foundation describes an ICD as a small device which is placed under the skin, is connected to the heart with “thin wires” and “sends electrical pulses to regulate abnormal heart rhythms”.

Boesen added: “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.”

Former Spurs player Eriksen, who is now at Inter Milan, collapsed shortly before half-time against Finland and needed to be resuscitated with a defibrillator.

German doctor Jens Kleinfeld, who treated him on the field, told Funke media group: “About 30 seconds later, he opened his eyes and I could talk to him directly.

“That was a very moving moment, because in such medical emergencies in everyday life, the chances of success are much lower.”

Kleinefeld said he asked Eriksen, “Well, are you back with us?”

The doctor said Eriksen answered, “Yes, I am back with you” and, “Damn, I’m only 29 years old”.

Kleinefeld added: “That’s when I knew the brain wasn’t damaged and he had fully returned.”

Denmark’s next game is against Belgium on Thursday (17:00 BST) when they return to the Parken Stadium, which was the scene of Eriksen’s collapse.

Belgium intend to kick the ball out of play in the 10th minute to take part in a minute’s applause for Eriksen, with Danish fans planning the gesture as a show of support.

Denmark players surrounded Eriksen as he received treatment on the pitch before he was taken to hospital.

The match resumed and was played to a conclusion two hours after the incident, with Finland going on to win 1-0.

“It has been some very special days, where football has not been the most important thing,” said Denmark captain Simon Kjaer.

“A shock, that will be part of me – part of all of us – forever. The only thing that is important and really matters, is that Christian is OK.”

He added: “We will enter the pitch against Belgium with Christian in our hearts and thoughts. It gives us peace in our minds, which allows us to focus on the game of football.

“We will play for Christian, and as always for all of Denmark. This is the greatest motivation for us all.”
