Speaking after the match, Boesen said Eriksen was “gone”, but swift treatment on the field of play and by hospital staff meant the Inter Milan midfielder was stabilised, and he was later able to send his greetings to team-mates.
Providing an update on Thursday morning, Boesen said: “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.”
