36 yrs. old female w/resting heart rate of 110. 5 mins. on the eliptical machine and it's 130-135 and about 30 min. it's 170-175 and I have dizzyness and a light headache with it. Had an echocardiograham about 1 1/2 yrs. ago and everything was fine. I always feel like Im out of breath and I breath a little heavier that normal. Father has heart disease and mother's sibblings have heart disease. Never smoked. My test was fine. What do I do now? Should I be concerned? Could this just be a norm for me. This has been going on for about 2 years.
