Sinus arrhythmia

Sinus arrhythmia is markedly irregular in the atrial nodes, making the rhythm of the atria and ventricles irregular. On the electrocardiogram recorded by the same lead, the difference between the longest PP interval and the shortest PP interval is more than 0.16s (some scholars have suggested that it is more than 0.12s).
