Hello, I am a 43 year old African-American female with a history of high blood pressure, and pre-diabetes. I have been experiencing VERY frequent intense heart palpitations, that can be felt in my chest, a fluttering in my throat and a sense of heaviness, lethargy, lightheadedness and mild shortness of breath at times, VERY frequent and irritating burping and belching. I feel as though I m having hundreds of palpitations/flutters per day, onset 5 days ago, usually noticeable while laying down and sitting upright. I have been taking Bisoprolol 10/6.5 for approximately 2 years and the palpitations that I was having at the time I was prescribed stopped for the past year and have now resurfaced. I also had a history of reflux/GERD and I tend to have some relief of the palpitations with a huge belch. I am not so much concerned about the GERD symptoms as much as I am with the fluttering and palpitations, which seem much more intense than before. Could the palpitations be associated with GERD?
