I just got a new Dr. Morepen pulse oximeter and while checking my heart rate and oxygen levels, it showed a message about a suspected occasional short pulse interval. Should I be concerned about this? I had a mild Covid infection last year and experienced some palpitations afterward, which have since improved over time. After recovering, I did a holter monitor test that was normal except for Sinus Arrhythmia, which my doctor said was normal. My Echo test in October also came back normal. I often check my pulse rate and oxygen because of occasional palpitations since the Covid infection. Do you think I need more tests because of this short pulse interval message?

An echo is advised to the patient.
