Since I was 18 I've had a tight sternum / upper chest area, with minor pain. I've also had acid problems since around the same time, and have been taking omeprazole (mostly) regularly since then. My dad has a hiatius hernia and acid problems also.
Anyway, the past 2 weeks I've been having heart palpitations, or something I have mistaken for palpitations. It is like a short sharp exhalation of air, from my nose after a spasm from my chest- area... (the "core" of me). It is very hard to pin down. It's like someone very quickly squeezes the air out of me. Completely involuntary. It's quite concerning. Sometimes I feel my heart beat, I think. This can happen 40 or so times a day. It gets worse throughout the day, it doesn't really happen in the morning, or if it does, it feels 'lighter'.
The doctor gave me an ECG in January - all clear. Blood tests last week - all clear. I mentioned my acid, and that I missed my tablets for a week or so, and he said it might be related, and re-prescribed them and told me to come back in a month of taking them again. He doesn't seem worried but I feel he's just pawning it off as Anxiety. I've been back on the omeprazole for 4 days now and its no different.
I was worried about a heart issue, but he said not to due to clear tests. However the ECG was in january, long before these palps... or whatever they are.
