I had the same thing. You should go to a doctor and get it checked out they will refer you to a cardiologist. The doctors never caught mine on an EKG. I had to wear a Holter monitor
for a week since mine did not occur very often. I had a tachycardia
. They normally are harmless, try to stay away from caffeine and try to monitor your heart rate
during exercise. You should find out which type of tachycardia you have because they will give you more information on it and let you know what the options for treating it. I had the options of leaving it be, taking medicine, or a minor surgery that corrects it.
