I am an active 62-year-old woman in good health. My total cholesterol is 189, my HDL is 74, and I take hormone replacement therapy. I have no problems with heavy yard work or low-impact exercise classes. But sometimes I get episodes of irregular heartbeats and occasionally experience tightness in my chest when walking up hills. I was told my stress test was slightly "irregular," but my doctor tells me not to worry. Should I be concerned?
