I have a question, while in clinicals I did my assessment and listened to the heart. It sounded regular to me, s1s2 but the RN that I was working with told me the patient had a history of Afib and that a patient with afib would always have an irregular heartrate no matter what. The patient was not on tele and was in the hospital for abdominal pain and the MD was still ordering xrays, blood stools, and all. For future reference, should I always hear an irregular heartrate with a patient who has a history of AFib or can it be a regular heartrate as I heard? Now I am doubting if I can hear heartrate regular and the pulses also felt regular for me too. Thank you.
