You need to watch for the triggers, caffine, spicy foods, lack of sleep,
stress,
stress and
stress. Does your heart feel like it skips a beat? Everyone has them, its just some people are hypersenstive to them and feel them more often. If, you have had all the normal test and they are ok, then ask your doc for a dfferent beta blocker or a calicum channel blocker, they help but they dont make them go away for good.
