“Heart rate too low’: Mette-Marit and Ingrid Alexandra rush to King Harald in the hospital. “The king has a heart rate that is too low and requires a permanent pacemaker,” said the palace’s official statement.

The timing of inserting a pacemaker depends on when the king is completely infection-free. This may take several days, so the King will probably stay at Rikshospitalet [Oslo University Hospital] over the weekend.
