I too have experienced this off and on for years. History of anxiety that I thought I had licked. GI problems. History of heart flutters. Overweight by about 30 lbs. Smoker. Gallbladder removed 6 years ago. Mild IBS with constipation and pretty severe fibromyalgia when not taking Lyrica (which is great for the fibri AND anxiety by the way).
I thought this flutter problem had pretty much gone away too (except for the truly occasional fluttering) until about a week ago when it kicked back up BIG TIME. Over this week it had become pretty much constant again...all day and night long.
I had previously been through all the cardiac and GI tests so I knew when mine resurfaced that it was not truly heart-related but more gastro with sympathetic cardiac symptoms. I also know that my increase in stress, smoking and caffeine has had an effect on this coming back with such intensity. However, even thought I knew all that...it is still scary because there is always that "...what if this time is different?"
So I went to my doctor (who is 'new' to this with me) and what has changed is that I foudn I am now lucky to have a very experienced physician who knew exactly what I was talking about when I described these feelings to him and was able to give a little more insight into why this could be happening to such an extent.
Of course, he mentioned the usuals...being overweight, smoking, vitamin and electrolyte deficiencies [which we tested for; no results yet], reflux, hernia [that I do have] and WAY too much caffeine, perimenopause and stress. But in lieu of a radical lifestyle change overnight, one thing he did suggest for immediate relief instead of a beta-blocker which is a pretty serious step for what was - at least for me - not truly 'cardiac', was an increase in magnesium. So, I went to the health food store across the street (convenient) and purchased 'Nature's Calm'. It is a magnesium powder and comes in different flavors to add to hot water to create a (pretty good tasting) 'hot tea'.
Started this two days ago and the difference is AMAZING!!! I am definitely no doctor but if you are having these flutters, I would at least give it a try. It's called 'Nature's Calm' because come to find out... many anxiety problems can go hand in hand with too little magnesium. It did calm me and it tasted pretty good too. And it has drastically reduced the number and severity of the flutters. A nice bonus (at least for me because I have mild IBS with constipation) is that it loosens the bowels gently in the right dose and that is apparently something I needed as well.
Just thought I would pass this along as it really has helped!
P.S. To KoReE, I would really pay attention to your feelings on Buspar. I have been on almost every anxiety med known to man (mine 'started' with Post Traumatic Stress Disorder after finding my best friend dead at 29 even though I had always had those tendencies) and Buspar is really tough for A LOT of people. Especially if you are the type of person who gets a little preoccupied with your health in times of anxiety (which many of us do) because Buspar can give some pretty intense dry mouth, dizziness and even increase anxiety
in many cases. My doc luckily told me this up front and told me what Buspar might make me
feel like. And it did. We gave it almost a month and when those icky feelings on Buspar didn't get better, put me on something else. Lexapro and Lyrica have helped both my fibromyalgia and anxiety. But I could not tolerate Buspar at all. Neither could my nephew. My aunt - on the other hand - loved it.
Just thought I would let you know so if you felt the way I did on this med, it wouldn't cause you more distress.
