What does sinus arrhythmia indicate?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hi doctor,

I am a 35-year-old male. I had an ECG done early in the morning, immediately after waking up from sleep, and it showed a heart rate of 60 bpm. Later that same day, I had another ECG at the hospital, which recorded a heart rate of 83 bpm. It was noted as a normal sinus rhythm with sinus arrhythmia. What does this mean?

Hi,

Welcome to icliniq.com.

Sinus arrhythmia is an entirely normal phenomenon. It simply means that the heart's pacemaker, the sinus node, responds well to everyday stressors and activities. It is natural to have a low heart rate of 60 beats per minute in the early morning and to see it rise to 83 beats per minute as your activity increases. Rest assured, all is well.

Wishing you all the best.
