According to the AASM scoring manual, a pause in the heart rate for 3 seconds or longer is called?

• A. Bradycardia
• B. Asystole
• C. Premature ventricular contraction
• D. Prolonged QT interval

Answer: (B)

In this context, the key idea is how the sleep study terminology classifies a pause in the heart’s rhythm. A pause lasting three seconds or longer is labeled asystole in the AASM scoring manual. This term is used to describe a pause where there is a cessation of ventricular activity for a noticeable interval, rather than just a slow heart rate or an extra beat. It’s different from bradycardia, which means a slow overall heart rate but not a pause; from premature ventricular contractions, which are early, extra beats; and from a prolonged QT interval, which refers to the length of a specific ECG measurement, not a pause in rhythm. So a three-second or longer interruption in rhythm is treated as asystole for scoring purposes.
