Just curious, not concerned: I have a Nonin Oximeter. Due to COPD I check my 02 saturation on occasion. Most of the time my heart rate might drift 1-2 bpm over the period of a minute or so. But every once in a while it will fluctuate 6-9 bpm w/in a minute or so, for instance from 61 to 70. Is this something that should be mentioned to the cardiologist the next time I see him? I have been Dx'd w/A fib and as far as I can determine medication has it nicely under control. I've not been aware of any A fib since the third day after starting medication.
