Question: Every once in a while I have the sensation that I have palpitations. It usually happens more a night time and I also noticed that my stomach feels very bloated and feels tight. I take medicine for anxiety for about a year now and before I started taking this medicine (lexapro) every time I had this scenario I would end up in an ER thinking I was having a heart attack. I've been seeing a cardiologist for the past year and a half. Initially he did several test , including an stress test, an echocardiogram, ekg, etc. all was normal to him but I see him every 6 months now and my visits are very short. He does an ekg and talks to me for about a minute and tells me that everything is fine. Sometimes I wonder and I'm hoping that he's not missing anything. Now, I also suffer of heartburn and acid reflux very often. I take medicine for this from time to time but I haven't been very consistent with it. Another thing that happens when I feel this sensations of palpitations is that sometimes I do pass gas and then I also wonder if this has anything to do with the feeling of the palpitations. Sometimes when I'm very careful to see what this sensation of palpitations are it makes me feel that it could be some air passing through my chest. Could this be possible? . Another scenario is when I go to bed I lay down on my side , whether right or left , and I also feel this sensation of palpitations. Any words of advice? What are your thoughts on this?
