Denmark midfielder Christian Eriksen will be fitted with a heart-starter device after his team's loss during their team's Euro 2020 opener against Finland on Saturday, the national team doctor said in a statement on Thursday.
Ericsson's life was saved when CPR was administered on the pitch and his heart was restarted with a defibrillator before being taken to the hospital, where he is recovering.
They will receive an implantable cardioverter defibrillator (ICD), a small electronic device that is a type of pacemaker and can prevent fatal cardiac arrest by discharging a shock to restore a regular heart rhythm.
Doctor Morten Boesen said in a statement: "Following several different heart tests, it has been decided that he should have an ICD." "This device is essential after a cardiac attack because of rhythm disturbances.
"Christians have accepted the solution and the plan has been ratified by experts nationally and internationally who all recommend the same treatment."
Netherlands defender Daly Blind still plays professionally for Ajax with an ICD. He underwent a fit in 2019 after he was diagnosed with swelling in the heart muscle.
Italian FA rules prohibit players from playing with internal defibrillators, so Ericsson will need special arrangements to return to Inter.
Meanwhile, Denmark captain Simon Kajar, who received widespread praise for his role in helping Ericsson so quickly after the collapse, said in a statement on Twitter: "It's been some very special days, where football is most important. The thing is not.
"A shock, that will be a part of me - a part of us all - forever! The only thing that is important and really matters, is that Christian is okay!!
“I am proud of how we worked as a team and how we stood together in these difficult times. I am so grateful and very grateful for everyone's support.
"Today, we will enter the pitch against Belgium with Christian in our hearts and thoughts. It gives peace to our mind, which allows us to focus on the game of football.
"We will play for Christian, and as always for Denmark as a whole. This is the biggest inspiration for all of us. As always: we will do our best!"
Denmark face Belgium in a game at noon ET in Copenhagen that Ericsson will watch from his hospital bed, manager Kasper Hjulmund said.
Belgium forward Romelu Lukaku, Ericsson's teammate at club level with Inter Milan, said his side would take the ball out of play in 10 minutes to pay tribute to the Danish midfielder.
One of the doctors helping to treat Ericsson on the field told German media that the midfielder could speak and think clearly soon after being revived with a defibrillator.
Jens Kleinfeld, a senior UEFA medical official, said the defibrillator was used after a few minutes of heart massage.
"After about 30 seconds the player opened his eyes and I was able to speak to him directly," Kleinfeld said in an interview with the Funke media group in Germany. "That was a very dynamic moment, because with such medical emergencies everyday the chances of success in life are very slim.
"Eriksson looked at me and I asked her: 'Well, are you back with us?' And he replied: 'Yes, I am with you again'.
Kleinfeld said that Ericsson also said: "Hey, I'm only 29."
"Then I knew the brain was not damaged and that it was fully restored," Kleinfeld said.
Kleinfeld said Ericsson can follow instructions to place a hand on his chest as they prepare to take him to the hospital.
UEFA sent a video to the Danish federation on Thursday containing messages of support for the other 23 teams in the tournament as well as the governing body's president, Aleksander Ceferin, and the referee's Eriksson. "I am very happy to see you in better and safer hands," said French goalkeeper Hugo Lloris, who was teammate with Ericsson at Tottenham.
Ceferin said the incident "made us all realize how fragile our lives are".
