I also take prilosec for acid reflux, I started having an irregular heart beat a few years ago while I was pregnant, and also taking
prilosec at the time. I had every test done on my
heart, ekg, ultrasound, even wore a holster
and they could find nothing wrong!! Over the past few years I have noticed a link between the arrhythmia and the prilosec, and there are many other people experiencing the exact same thing!
