Hello, I am a 60 year old male in relatively good condition and fairly active, not on any medications, blood pressure runs 120-130 over 78-84, borderline high cholesterol and very little history of heart problems in my family. Occasionally my heart beat is irregular...no fluttering, sometimes skips a beat or 2-3 fast beats in a row that usually doesn t last very long, but I usually can tell because I feel anxious. I have no other symptoms of heart problems that I m aware of. Should I be concerned?
