Danish footballer Christian Eriksen to be fitted with heart-starting device

The video discusses Danish soccer player Christian Eriksen's need for an implantable cardioverter defibrillator (ICD) following a health incident during a European Championship game. It explains the function of ICDs, which are devices implanted in the chest to treat arrhythmias by regulating the heart's electrical signals. The heart's electrical system is crucial for maintaining proper heart function, and any disruption can lead to cardiac arrest. ICDs help by monitoring heart rhythms and delivering electrical pulses to correct irregularities.
