Chronotropic Incompetence
I recently took a Holter monitor test and the interpretation was:

Chronotropic incompetence with very low HR range.
Occasional PVCs and PACs

My Average HR was 66
Minimum HR:  42 BPM (1428 msec)
Maximum HR:  91 BPM (659 msec)

I am 58 years old.  I don't understand what the Chronotropic incompetence reference means.  I don't have a follow up with my doctor for a month.

Thank you.

Chronotropic incompetence means that your heart rate does not increase the heart rates that would be expected for your age.  An exercise stress test is a better means to determine how high  your heart rate will go because we know exactly how much you exerted yourself.

Unless you are having significant symptoms of shortness of breath, fatigue or decreased exercise tolerance, this is unlikely clinically significant.

Thanks for posting.
