So, I recently found out I have gallbladder stones and I'm going to have laparoscopic surgery soon. As part of the prep, they did some tests and my ECG came back showing Sinus Arrhythmia. I'm a bit worried and wondering if that's something I should be concerned about. Do you think my ECG is normal, or could there be an issue there? Also, if there is a problem, would it affect my upcoming surgery? I've also been dealing with some symptoms that might be related, like really bad acidity for the past four months, frequent burps and hiccups, feeling nauseous, and pretty intense acid reflux. It's like a liquid moves up my food pipe to my throat and causes pressure in my chest and around my food pipe. Also, I often feel short of breath during the day, but it seems to get better when I lie down. Do you think this shortness of breath is because of the gallbladder or could it be a cardio issue linked to the ECG results?
