I had a resting heartrate of 78 this morning for 2 hours?

There is nothing abnormal in your resting pulse rate being 78. Your symptoms do not seem to be heart related. If you feel chest pain during activity, you might suspect a heart deficiency. I think your symptoms might be more related to nervous problems. It seems that you are either young, or middle-aged. Try to manage your stress. I would suggest that you see a neurologist and discuss the matter with him. What about alcohol, smoking, and coffee? Are you protecting yourself from them?
