I also have a concern related to one posted by Peter with respect to acid reflux and arrythmia, and to this one about lo energy. I have been treated for GERD for about 4 -5 years, and am recently on Prevacid, again, which I find far more helpful than small meals, dietary restrictions, and not eating within four hours of bedtime. I too, experience occasional rapid heart rate, palpitations, which subside within a minute, and they seem to be correlated with a sensation of stomach fullness and swallowing. I also have been very tired and with low energy, despite treatment with Paxil for depression. I also have a hx of heart murmur as child and young adult, though none of my doctors since adulthood has ever mentioned that I have a murmur.
I have also noticed that reflux symptoms are worse duing pre-menstrual phase of cycle. I am 50, and there is a strong family hx of heart disease in my father, his siblings, and in my mother's siblings. I am concerned I won't be able to distinguish a pending heart attack from the usual reflux and related problems.
have you been checked for mitral valve prolapse? it can cause al of the symptoms you describe.
I too must admit I don't know what is going on. However, if the medications are helping I would probably keep taking them. Good luck.
