I think so: I think ur asking if a heart rate of 81 when you are not resting (so perhaps after you exercise?) is a safe rate; if that's correct then yes 81 is probably fine.

No: That heart rate isn't dangerous but it's unclear whether or not it's normal. If you've been active, anxious, have fever, pain, thyroid excess, anemia etc., it may be appropriate.
