Sinus block occurs when the impulse generated by the sinus node is not conducted out of the sinus node. This can result in a pause between normal sinus beats. Sinus arrest is a more severe form of sinus block where the pause is longer and can result in symptoms. Sinus arrhythmia is a normal variation in the rate of the sinus node and is not associated with pauses or blocks. Sinus bradycardia is a slower than normal rate of the sinus node, but not necessarily associated with pauses or blocks.
