Heart fluttering, skipping beats

Do you notice the symptoms at night when in bed? How often do you feel the fluttering? I have had this happen to me since mid 40's. My heart would flutter for about 15-30 secs then return to normal. When I first went to the Dr he asked how much vitamin c I was taking then advised me to stop the c supplement. The explanation I got was that your heart is in a sac of fluid when the fluid gets more acidic it messes up the electrical pulses. Stopped the vitamin c and all was well until I started drinking coffee in my mid 50's. The second time I went to see a Dr was in my early 60's it was caused by excessive caffeine, 2 travel mugs of coffee in the morning which is equivalent to 6 cups. A stop at McDonalds for lunch and several diet cokes added more caffeine. Reduced coffee to one mug and went to caffeine free soda and the problem has virtually gone away. Stress tests and echo cardiograms can't find A fib, all of which I have had. The Dr told me if the problem still exits a heart rate monitor would have to be worn to record your pulse over time. Try reducing your caffeine and C supplements and see if your symptoms get better. Hope your heart rate returns to normal.
