4-month-old with extrasystoles on auscultation at pediatrician’s office

Case

I have a 4-month old male in my office today for a well-infant check, who is growing well and doesn’t appear to have any clinical concerns but when I listen on cardiac exam, I am hearing some extra beats or changes in rhythm that seem a bit off. I’m thinking I should send him to you for evaluation. Should I order an event monitor or something first?
