I am 42, female, dignosed 2 1/2 years ago with mild mitral/ tricuspid regurgitaion, after Dr. said for years he could hear it and ordered an echo. GP told me it was something to watch, but told no need for prophylactic antibiotics, etc. Mother had a stint placed for a blockage when she was 58, had no warning signs of heart disease, low BP, low chol., not overweight, then had a brain bleed at 61 and is permanently disabled. I too am not overweight, have low chol., 117/74 average BP. I have had PVC's all my life, probably 100+ a day, but have been told this is benign. I work out (Jazzercise) 3-4 times a week, for 10 years. When I work out my heart rate quickly gets to the top of my target heart rate zone, and I have to cut back on effort considerably to keep it in range. In general my pulse rate is always higher than average. Question: When should I consider seeing a cardiologist? The echo was ordered by my GP, and there was no recommendation at the time for referral.
