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.

Does everyone have respiratory sinus arrhythmia? Is it normal? Would my doc detect this by having me breathe deep while listening to my heart?

Was looking at a test result from 3 yrs ago & it said sinus rhythm, possible left atrial enlargement. No one ever told me! I do have bad arrhythmias sometimes & now Im wondering if that could be why. Should I be worried & request an echo?
