I have genetic high cholesterol, it's not controlled by anything I eat, borderline high blood pressure, and possibly something wrong with my heart rate. Sometimes I'll freak myself out when I get my heart working hard and I hear my heart rate in my ears(does this happen to anyone else?). Then I stop exercising for a day or two and then start again. I'm fit and eat really healthy, is there anything I should be worried about??
Familial hypercholesterolemia should not affect the heart. As long as you have regular doctor visits you should be fine. However, if you ever pass out you should get a test for your heart called an ekg. If you are still worried and need some reassurance, go to your doctor and tell him or her that you have heart palpitations and that you request an ekg. They might do it for you.
