Sinus Arrest (a.k.a. sinus pause) occurs when the SA node fails to fire. The resulting pause is often NOT equal to the multiple of P-P intervals seen in the Sinus Exit Block. Instead, often an escape pacemaker such as the AV junction will assume control of the heart. Again, like the Sinus Exit Block, treatment is related to the frequency and duration of the periods of sinus arrest.
