Final answer:
New onset Afib and proptosis are unrelated conditions.
Step-by-step explanation:
The relationship between new onset Afib (atrial fibrillation) and proptosis (bulging of the eyes) is that they are unrelated conditions. New onset Afib refers to the sudden onset of an irregular heartbeat, while proptosis is often associated with conditions such as thyroid eye disease or orbital cellulitis.
Although both conditions can occur in the same individual, they do not have a direct cause-and-effect relationship. It is important to note that each condition has its own underlying causes and should be evaluated and treated separately.
