I have a slow heart rate, also extra beats, which they tell me are benign. stress test ok, my thyroid is stable with meds. why do i have these symptom?

Stress, Perhaps: Learn to relax deeply and let go of stress, and especially any anxiety or inner pressure (http://drmiller.Pinnaclecart.Com/balance-mind-and-emotions/abolish-anxiety-2-cds/28 is a valuable program). Sometimes the generalized irritability of the nervous system may have a role to play. If a week of sheer relaxation in a vacation place diminishes the extra beats, think stress. More at drmiler.Com.

Possibilities...: ..Include low serum potassium (from anti-bp or other rx), "escape" heart beats that occur when one's hr is unusually low from stress, rx, exercise fitness or underlying alternative electrical cardiac pathways. Not a bad idea to seek cardiology advice.
