Normal: Sinus arrhythmia is the normal speeding up and slowing down of your heart as you breathe so your heart can adjust to the changes in blood flow as the lungs expand and contract. Everyone has this.

The word "arrhythmia" is scary! But as Dr Buckler notes, sinus arrhythmia is a normal condition that does not cause any problems.
