-Under certain circumstances, the [[SA node]] fails to initiate an impulse at the expected time in the [[cardiac cycle]]. In the absence of an impulse from the SA Node neither the atria or the [[ventricle]]s are stimulated and thus an entire PQRST complex drops out for 1 beat(or more). This is called Sinoatrial(SA) Arrest. In other instances the impulse is initiated normally but is blocked within the SA Node and never reaches the atria and ventricles.
