Hi..I had an endoscopy and a colonoscopy in June. I just turned 50 and was having upper right quadrant pain that I thought may be related to being on 4 antibiotics in 2 months, so the doctor ordered both tests. The gastro doc said I had mild gastritis and GERD (even tho I never have heartburn), he removed a benign nodule from my esophagus and said I had diverticuli that were not inflamed. About 2 weeks later I had severe chest pain and heart pounding. Went to ER and everything was OK. Then I started having PSVT (160 - 190 bpm)--once they were brought on by burping and once by bending over. These episodes became more frequent with runs of A-FIB. (These beats were caught on an event monitor.) I am taking a beta blocker to stop these wacky heartbeats, but I think these may have been triggered by the endoscopy. Is that possible? Could I have some kind of infection? I have lost 20 pounds in 6 weeks and a lot of times eating makes these beats worse. Does anyone have any insight to this mess? Also I am taking Prevacid for my supposed heartburn. Thanks for any and all help. God Bless.
