Hi doctor,

I am a 35 year old male. I had an ECG done early in the morning immediately after waking up from sleep. It was 60 bpm. Later, on the same day, I took another ECG in the hospital and it was 83 bpm. It was mentioned on as a normal sinus rhythm with sinus arrhythmia. What does it mean?

Welcome to icliniq.com.

  • Sinus arrhythmia is an entirely normal phenomenon. It just means your pacemaker of the heart. The sinus node will react well to everyday stressors and activity. It is natural to have a low heart rate of 60 during early morning and 83 as your activity progresses.

Be assured. All the best.
