I too believe that gallbladder disease caused 90% of my pacs and pvcs. I have had palpitations for the last 20 years which increased greatly over the last 12 years. I also had acid reflux and heatburn everyday. I had a lone episode of afib in 08 so have been under care of cardiologist since. After thorough heart exams, with nothing serious found, was put on beta blocker. Continued to have frequent palpitations (numerous episodes daily). I have found through experience over the years, there are several things that I feel cause the palpitations, i.e. cold medicines, dental anesthetics, over full stomach and always after eating. Sometimes the palpitations would start while I was eating, a couple of times, so sever I felt I would faint. In Jan. of 2012 I started having pretty severe pain in my back, right side, midway between shoulder blade and waist, some tenderness under ribs in front. The pain would start at night when I would lie down.
To make a long story short, because of increase in palpitations my cardio dr. had me on a heart monitor when my pcp sent me for scan because of back pain. Found I did have gallstones and sludge. I had surgery in April 2012 for removal of gallbladder.
About three months after surgery my palpitations had improved by , at least 35%. As I write this, which I am now 9 months post surgery, I can say the number of palpitations I have, has gone from too many to count daily (and always some of them after eating) , to one or two daily (usually these occur when I get hungry) .
So, I have to say, maybe not scientifically proven, but according to my experience, a diseased gallbladder most definitely effected my palpitations in a negative way. WOW-I am so SHOCKED.
I believe 20 years ago I may have been where you are today.
Hope this helps you.
