After detailed heart examinations, the doctors have come to the conclusion that Christian Eriksen should have a so-called ICD implanted under the skin.

It can be described as an automatic pacemaker that senses the rhythm and gives a shock if there is a cardiac arrest.

- An implanted ICD means that it has been assessed that he is in need of one so that it could happen again, says Mats Börjesson.

There are examples of football players who have continued to play with an ICD, but there are several things to consider.

- The most important thing is to find out the underlying cause.

It is not always possible to find out, but it can be the case that certain diseases are aggravated by playing sports and then the risk of it happening again increases.

Then it is not relevant to continue playing sports.

With other diseases, it may be possible to play sports, says Börjesson.

The doctor also says that the risk of getting shocks from the ICD without it being necessary increases during physical activity.

- It is incredibly unpleasant if it should happen, he says.

Another important factor is that the device can be damaged if you are doing a contact sport such as football.

- In the event of a blow to the chest, the system may be destroyed.

There is less tendency to continue with a contact sport such as football, but there are football players who have continued.

Finally, there will be a discussion between the attending physician and the individual where all these things are weighed.

- If you have a contact sport and a disease that can be aggravated by it, you do not usually recommend it.

At present, it is not clear what was the underlying cause of Eriksen's cardiac arrest last Saturday.
