Ronkers was getting out of the elevator on the first floor when the intercom paged 'Dr Heart'. There was no Dr Heart at University Hospital. 'Dr Heart' meant someone's heart had stopped.
'Dr Heart?' the intercom asked sweetly. 'Please come to 304 . . .'
Any doctor in the hospital was supposed to hurry to that room. There was an unwritten rule that you looked around and made a slow move to the nearest elevator, hoping another doctor would beat you to the patient. Ronkers hesitated, letting the elevator door close. He pushed the button again, but the elevator was already moving up.
'Dr Heart, room 304,' the intercom said calmly. It was better than urgently crying, 'A doctor! Any doctor to room 304! Oh my God, hurry!' That might disturb the other patients and the visitors.
