hello, im a 20 year old non smoking male, who is in decent shape. im 6'3 210 lbs. this has been happening for the last couple years...ill perform a task that is of no physical strain and randomly my heart rate will jump from like 70bpm to around 130bpm.

this has happend from swinging a golf club, bending over, walking, getting up, or just standing still. so it seems quite random for this to be happening.

to slow my rate down i will start to breathe slowly and deeply as this can last anywhere from 1 to 8 minutes!

just wondering if this is something serious and if i should get it checked out by a doctor, or if its something to not worry about!
thanks!
