I Am 21, Almost 22 And My Resting Bpm Is

I am 21, almost 22 and my resting bpm is 92. It was in the mid 80's when I saw my doctor last week and has always been high (since high school at least). My doctor has said in the past that it sounds "a little tachycardic". Given this information, is my bpm something to be concerned about? (In regards to overall health concerns due to such results)
