Overview

Sinus arrhythmia is a variation in the rate of the SA node. It is the most common type of arrhythmia and is considered to be a normal variant. It is more common in the young, especially with slower heart rates or after enhanced vagal tone. It also decreases with age or with auatonomic dysfunction. The formal definition of sinus arrhythmia is a variation in the P-P interval by 0.12 sec (120 msec) or more in the presence of normal P waves and the usual PR interval. There are two types of sinus arrhythmia: respiratory, or phasic; and nonrespiratory, or nonphasic.
