NICU infant noted to have extrasystoles on cardiac monitor

Case

You receive a call from the neonatal intensive care unit (NICU) regarding an ex-34 week premature infant. “I have this 1 week old male infant who is here for a persistent oxygen requirement and feeding issues. The baby was intubated after delivery but now has weaned to 1 liter of oxygen via nasal cannula. The baby has been on parenteral nutrition but is receiving some feeds via nasogastric tube. Because he is on oxygen, he requires monitoring and we have noted extra beats that causes his monitor to alarm. Could you come by and take a look?”
