So what if I'm just sitting at my desk at work, when suddenly my heart goes an unaware 65bpm to a noticeable 80-pounding-in-chest bpm and back?
i wouldn't worry too much. now if it goes to 120+ I would go see a specialist. my friend has tachycardia episodes where his heart beat will go from 70 to 150+ and sometimes more. it runs in his family and his brother has it as well.
