Before the question of borderline can be answered and relevant ...borderline of what category...blood pressure, ejection fraction, heart rate (rest, exercise), etc. :)
there is no right answer...just a point of view - optimistic or pessimistic. Let the philosophers debate the half glass of water.
:) I think your answer is the right one. What I meant is also..still normal, but almost not normal.:).....if we put abnormal over normal ...but if we put in under....OK....I'll stop ..
...it reminds me if the "glass is half full or half empty?"
sorry to be the pessimist but it couldes also mean the lower limit of normal as well... need to know more information than "borderline"
borderline is if the heart is at the very upper limit of normal.
