what is the meaning of the vertical lines in my heart rate app?
I have those vertical lines on my heart app and would like to now how to read that?
If I have a full line from 50 to 140 does that mean that my heart rate went suddenly from 50 to 140?
If I have a dotted line 50 to 75 and then another one on top of the first one 80 to 140, how to read that
