Episodes of extreme tiredness, lightheadedness, palpitations

[Alyjod3]

I get these episodes that come and go. Could be days, or weeks in between. It usually starts off with feeling very tired all of a sudden, then lightheaded with tunnel vision. A lot of tomes when this happens I will also get 1-5 skipped or fluttery heart feelings which take my breath away. I have had a holster monster which was normal, my stress test was normal. My echo came back saying I had diastolic dysfunction, and trace regurgitation in, I think 2 valves. I've been told the diastolic dysfunction doesn't really cause symptoms. Any ideas to what could cause these episodes?

Also, I am 28 and female. With a history of anxiety disorder.

It's really hard to say.  It is possible the anxiety you have is outputting stress hormones that your body sometimes reacts to maybe after you have had a stressful time.  Our nervous system and heart are closely tied.  If your nervous system is on overload it could start to affect the heart so try and get your anxiety under control.  Maybe take up yoga or mediation.  See a therapist or try anxiety meds and see if it helps.  In an otherwise healthy heart the flutters you feel are really of no danger.  They are more fear provoking than anything else so try to not let them take over your thoughts.  Avoid caffeine, sugary foods, foods high in carbohydrates and spicy foods.  Attend to any acid reflux and try to not over eat at your meals.  As well make sure you are properly hydrated and see if that helps calm them down.  and do your best to get on top of the anxiety.  The fluctuation in stress hormones may be throwing your nervous system off contributing to your symptoms.  Best of luck getting on top of things and try to not worry.  Take care and keep us posted on how you are doing.
